Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This patent application is based on and claims priority under 35 U.S.C. .sctn. 119 to Japanese Patent Application Nos. 2007-202385 filed on Aug. 2, 2007 and 2008-154521 filed on Jun. 12, 2008, in the Japanese Patent Office, the entire contents of each which is hereby incorporated herein by reference.

FIELD OF THE INVENTION

[0002] Example embodiments of the present invention generally relate to an apparatus, method, system, computer program and product each capable of controlling an image processing system, and more specifically relate to an apparatus, method, system, computer program and product each capable of controlling an image processing operation to be performed by an image processing system having a plurality of apparatuses connected via a network.

BACKGROUND

[0003] Recently, a plurality of image forming apparatuses may be shared by a plurality of client apparatuses through a network. In such case, each client apparatus needs to be provided with a printer driver specific to each one of the plurality of image forming apparatuses on the network. Without the printer driver being installed, the client apparatus is not capable of generating a printing job having a format specific to each image forming apparatus. For this reason, each client apparatus is usually provided with more than one printer driver. Further, the printer driver being installed on the client apparatus needs to be maintained to be the current version, for example, when the firmware of the image forming apparatus is updated due to the addition of a new image forming function.

[0004] Further, the printer driver, which is installed on the client apparatus, works on an operating system (OS) of the client apparatus such that the printer driver needs to be designed based on the OS. If the client apparatus is provided with more than one OS, or the OS with different versions, the client apparatus is required to install the printer driver specific to each type or version of the OS. Further, the printer driver being installed on the client apparatus needs to be maintained to be the current version, for example, when the version of the OS is updated.

[0005] As described above, management of one or more printer drivers in each client apparatus, which is usually operated by the human, has been cumbersome. In view of these limitations, Japanese Patent Application Publication No. 2004-7346 describes an image forming apparatus capable of providing a plurality of image forming functions, without requiring a computer terminal to install a plurality of drivers. However, the Japanese Patent Application Publication No. 2004-7346 does not describe the case in which the user desires to perform various processing before or after image forming, which is not supported by the image forming apparatus.

[0048] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "includes" and/or "including", when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

[0049] In describing example embodiments shown in the drawings, specific terminology is employed for the sake of clarity. However, the present disclosure is not intended to be limited to the specific terminology so selected and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner.

[0050] Referring now to FIG. 1, a configuration of an image processing system is explained according to an example embodiment of the present invention. The image processing system of FIG. 1 includes an image forming apparatus 1, an information processing apparatus 2, a session management server 3, a service management server 4, and a service providing server 5. The image forming apparatus 1 and the information processing apparatus 2 are connected to a first network A. The session management server 3, the service management server 4, and the service providing server 5 are connected to a second network B. In this example, the first network A and the second network B may each be implemented by a local area network (LAN), for example. Further, the first network A and the second network B are connected to a third network C, such as the Internet. Further, in this example, it is assumed that the first network A corresponds to a network of a user using the information processing apparatus 2 and the image forming apparatus 1. It is further assumed that the second network B corresponds to a network of a service provider providing the communication service to the user. Further, in this example, at least a portion of the first network A, the second network B, and the third network C may be collectively referred to as the network N.

[0051] The image forming apparatus 1 may be implemented by any desired image forming apparatus capable of performing image forming operation including, for example, a printer apparatus, a facsimile apparatus, a scanner apparatus, or a multifunctional apparatus capable of performing a plurality of functions including scanning, faxing, printing, or copying. The image forming apparatus 1 is further provided with the function of communicating via the network N. Further, as described below referring to FIG. 18 or 20, any number of the image forming apparatus 1 may be provided on any location on the network N.

[0052] The information processing apparatus 2 may be implemented by any desired apparatus having a processor and a memory, which may be provided with the function of communicating via the network N and the function of interacting with the user. The information processing apparatus 2 may be implemented by, for example, any desired computer, personal digital assistant (PDA) device, mobile phone, car navigation system, digital camera, digital video, etc.

[0053] The session management server 3 and the service management server 4, which may be collectively referred to as an image processing management apparatus 6, may together control operation of the image processing system of FIG. 1. For example, the session management server 3 may provide the function of managing communication among a plurality of apparatuses provided on the network N. At least one of the session management server 3 and the service management server 4 may provide any one of a plurality of functions including, for example, the function of managing various information regarding the plurality of apparatuses provided on the network N such as device information obtainable from the plurality of apparatus on the network N, the function of determining how an image processing operation is performed by at least one of the plurality of apparatuses provided on the network N, the function of determining how a data transferring operation is performed by at least one of the plurality of apparatuses provided on the network N, the function of determining how an image forming operation is performed by at least one of the plurality of apparatuses provided on the network N, and the function of determining how a post processing operation is performed by at least one of the plurality of apparatuses provided on the network N. The image processing management apparatus 6 may be implemented by any number of devices, for example, depending on a specific function to be provided. Further, the image processing management apparatus 6 may be implemented by any number of devices each having a processor and a memory.

[0054] The service providing server 5, which may be implemented by any number of devices each capable of communicating via the network N, may provide a specific service to any one of the plurality of apparatuses provided on the network N via the network N according to an instruction received from the image processing management apparatus 6. The service providing server 5 may be implemented by any desired apparatus having a processor and a memory, which may be provided with the function of communicating via the network N and the function of providing a function such as an image processing function.

[0055] In one example operation, at least one of the image forming apparatus 1 and the information processing apparatus 2, which may be referred to as a client apparatus, may receive a user instruction for applying image processing to input data to generate output data. The input data may be generated or edited by the information processing apparatus 2. Alternatively, the input data may be obtained by the image forming apparatus 1 by scanning an original document. Further, the input data may be stored in any location on the network N, such as in a storage provided in any one of the apparatuses provided on the network N. When the user instruction is received, the client apparatus may generate an image processing request, which includes image processing information regarding image processing to be applied to the input data to generate the output data, and send the image processing request to the image processing management apparatus 6 via the network. When the image processing request is received, the image processing management apparatus 6 may determine whether any one of the apparatuses provided on the network N is capable of applying the image processing specified by the image processing information to generate a service determination result. For example, the image processing management apparatus 6 may receive device information from the apparatuses provided on the network N such as the service providing server 5, and store the device information in a storage provided on the network N. Using the device information, which includes image processing function information indicating an image processing function to be provided by the service providing server 5, for example, the image processing management apparatus 6 may generate the service determination result. When the service determination result indicates that the service providing server 5 is capable of applying the image processing specified by the image processing information, the image processing management apparatus 6 may generate an image processing instruction that causes the service provider server 5 to apply the image processing to the input data to generate the output data. The image processing management apparatus 6 may send the image processing instruction directly to the service providing server 5 or via another apparatus provided on the network N such as the client apparatus.

[0056] After applying the image processing specified by the image processing information, the service providing server 5 may store the output data in any storage provided on the network N according to an instruction received from the image processing management apparatus 6. Alternatively, the service providing server 5 may send the output data to which the image processing is applied to any apparatus, such as the image processing management apparatus 6 or the client apparatus, according to an instruction received from the image processing management apparatus 6.

[0057] In the above-described example of processing the image processing request, when the service determination result indicating whether the service providing server 5 is capable of applying the image processing specified by the image processing information indicates that there is more than one device of the service providing server 5, the image processing management apparatus 6 may select one of the devices of the service providing server 5, for example, based on the device information of the service providing server 5 such as the address information or the status information.

[0058] In the above-described example of processing the image processing request, when the image processing specified by the image processing information includes a plurality of image processing operations, and the service determination result indicates that a plurality of devices of the service providing server 5 applies at least one of the plurality of image processing operations, the image processing management apparatus 6 may further determine an order of applying the plurality of image processing operations to generate a processing order determination result to cause the service providing server 5 to apply the plurality of image processing operations in the order specified by the processing order determination result. For example, the image processing management apparatus 6 may generate route information based on the processing order determination result, which indicates a route of transferring the image data from one device to another device of the service providing server 5. Based on the route information, the image processing management apparatus 6 may generate an instruction, such as an image transfer instruction or an image processing instruction.

[0059] In another example operation, at least one of the image forming apparatus 1 and the information processing apparatus 2, which may be referred to as the client apparatus, may receive a user instruction for forming an image of image data. The image data may be generated or edited by the information processing apparatus 2. Alternatively, the image data may be obtained by the image forming apparatus 1 by scanning an original document. Further, the image data may be stored in any location on the network N, such as in a storage provided in any one of the apparatuses provided on the network N. Further, the image data may be processed image data to which image processing is applied by, for example, the service providing server 5. When the user instruction is received, the client apparatus may generate an image forming request, which includes image data information regarding a data format of the image data, and send the image forming request to the image processing management apparatus 6 via the network N. When the image forming request is received, the image processing management apparatus 6 may determine whether the image forming apparatus 1 is capable of interpreting the data format of the image data to generate a service determination result. For example, the image processing management apparatus 6 may receive device information from the image forming apparatus 1, and store the device information in a storage provided on the network N. Using the device information, which includes data format information regarding a data format interpretable by the image forming apparatus 1, for example, the image processing management apparatus 6 may generate the service determination result. When the service determination result indicates that the image forming apparatus 1 is capable of interpreting the data format of the image data, the image processing management apparatus 6 may generate an image forming instruction that causes the image forming apparatus 1 to form an image of the image data. The image processing management apparatus 6 may send the image forming instruction directly to the image forming apparatus 1 or via another apparatus provided on the network N such as the information processing apparatus 2.

[0060] In the above-described example of processing the image forming request, information regarding the data format of the image data may be directly obtained from an image data file, for example, when the image data file is being sent to the image processing management apparatus 6 together with the image forming request.

[0061] In the above-described example of processing the image forming request, when the service determination result indicates that the image forming apparatus 1 is not capable of interpreting the data format of the image data, the image processing management apparatus 6 may determine whether any one of the apparatuses on the network N, such as the service providing server 5, is capable of applying data conversion to cause the image data to be converted to the data format interpretable by the image forming apparatus 1 to generate a determination result. For example, the image processing management apparatus 6 may receive device information from the service providing server 5, and store the device information in a storage provided on the network N. Using the device information, which includes image processing function information indicating an image processing function to be provided by the service providing server 5, for example, the image processing management 6 may generate the service determination result. When the service determination result indicates that the service providing server 5 is capable of applying the data conversion, the image processing management apparatus 6 may generate a data conversion instruction that causes the service providing server 5 to apply the data conversion to the image data to be in the data format interpretable by the image forming apparatus 1. The image processing management apparatus 6 may send the data conversion instruction directly to the service providing server 5 or via another apparatus provided on the network N such as information processing apparatus 1.

[0062] In the above-described example of processing the image forming request, when the service determination result indicating whether the service providing server 5 is capable of applying the data conversion indicates that there is more than one device of the service providing server 5, the image processing management apparatus 6 may select one of the devices of the service providing server 5, for example, based on the device information of the service providing server 5 such as the address information or the status information.

[0063] In another example operation, at least one of the image forming apparatus 1 and the information processing apparatus 2, which may be referred to as the client apparatus, may receive a user instruction for applying post processing to a sheet having an image formed thereon. The sheet with the image may be generated by the image forming apparatus 1. When the user instruction is received, the client apparatus may generate a post processing request, which includes post processing information regarding post processing to be applied to the sheet with the image, and send the post processing request to the image processing management apparatus 6 via the network. When the post processing request is received, the image processing management apparatus 6 may determine whether any one of the apparatuses provided on the network N is capable of applying the post processing specified by the post processing information to generate a service determination result. For example, the image processing management apparatus 6 may receive device information from the apparatuses provided on the network N such as the image forming apparatus 1, and store the device information in a storage provided on the network N. Using the device information, which includes post processing function information indicating a post processing function to be provided by the image forming apparatus 1, for example, the image processing management apparatus 6 may generate the service determination result. When the service determination result indicates that the image forming apparatus 1 is capable of applying the post processing specified by the post processing information, the image processing management apparatus 6 may generate a post processing instruction that causes the image forming apparatus 1 to apply the post processing to the sheet with the image. The image processing management apparatus 6 may send the post processing instruction directly to the image forming apparatus 1 or via another apparatus provided on the network N such as the information processing apparatus 2.

[0064] In the above-described example of processing the post processing request, when the service determination result indicating whether the image forming apparatus 1 is capable of applying the post processing indicates that there is more than one apparatus of the image forming apparatus 1, the image processing management apparatus 6 may select one of the apparatuses of the image forming apparatus 1, for example, based on the device information of the image forming apparatus 1 such as the address information or the status information.

[0065] In the above-described example of processing the post processing request, when the service determination result indicates that the image forming apparatus 1 or any other image forming apparatus provided on the network N is not capable of applying the post processing specified by the post processing information, the image processing management apparatus 6 may send a notice to the client apparatus.

[0066] In another example, at least one of the image forming apparatus 1 and the information processing apparatus 2, which may be referred to as the client apparatus, may receive a user instruction to transfer image data from a first apparatus to a second apparatus via the network N. The image data may be generated or edited by the information processing apparatus 2. Alternatively, the image data may be obtained by the image forming apparatus 1 by scanning an original document. Further, the image data may be stored in any location on the network N, such as in a storage provided in any one of the apparatuses provided on the network N. Further, the image data may be processed image data to which image processing is applied by, for example, the service providing server 5. When the user instruction is received, the client apparatus may generate an image transfer request, which includes information regarding the first apparatus and the second apparatus, and send the image transfer request to the image processing management apparatus 6 via the network N. When the image transfer request is received, the image processing management apparatus 6 may determine whether the first apparatus and the second apparatus are each capable of communicating to generate a service determination result. For example, the image processing management apparatus 6 may receive device information from the first apparatus and the second apparatus, and store the device information in a storage provided on the network N. Using the device information, which includes status information regarding a current status of the first apparatus and the second apparatus, for example, the image processing management apparatus 6 may generate the service determination result. When the service determination result indicates that the first apparatus and the second apparatus are capable of communicating, the image processing management apparatus 6 may generate a session start instruction that causes the first apparatus and the second apparatus to establish a session. The image processing management apparatus 6 may send the session start instruction to at least one of the first apparatus and the second apparatus, or via another apparatus provided on the network N such as the information processing apparatus 2. After the session is established, the image data may be transferred from the first apparatus to the second apparatus.

[0067] In the above-described example of processing the image transfer request, alternatively, the image processing management apparatus 6 may establish a session respectively with the first apparatus and the second apparatus. In such case, the image data may be transferred from the first apparatus to the second apparatus via the image processing management apparatus 6.

[0068] The image processing system of FIG. 1 may be implemented in various other ways. For example, the service providing server 5 may be integrated within the image processing management apparatus 6. In another example, any number of devices of the service providing server 5 may be provided on the first network A as illustrated in FIG. 1. In another example, any number of devices of the image processing management apparatus 6 may be provided on the first network A. In another example, the image forming apparatus 1 may be provided on the second network B. In another example, the image processing management apparatus 6 and at least one of the image forming apparatus 1, the information processing apparatus 2, and the service providing server 5 may be provided on the network N. In another example, any one of the information processing apparatus 2, the image forming apparatus 1, and the service providing server 5 may collectively referred to as a service providing apparatus based on the function to provide a specific service to the image processing system of FIG. 1.

[0069] Referring now to FIG. 2, an example structure of the image forming apparatus 1 is explained according to an example embodiment of the present invention. The image forming apparatus 1 includes a controller 100, an automatic document feeder (ADF) 101, a scanner 102, an output tray 103, an operation panel 104, a document tray 105, a printer engine 106, an output tray 107, and a network interface (I/F) 108, which may be electrically coupled or connected with one another as the arrows indicate. The controller 110 includes a main controller 111, an engine controller 112, an input/output (I/O) controller 113, an image processor 114, and an operation panel controller 115, which may be connected or coupled via an internal bus.

[0070] The operation panel 104 may function as a user interface, which allows a user to input various information to the image forming apparatus 1, for example, by providing an input device such as various kinds of keys or buttons that may be pressed or selected by the user, a microphone, etc. Alternatively or additionally, the operation panel 104 may function as a user interface, which allows a user to obtain various information output by the image forming apparatus 1, for example, by providing an output device such as a display or a speaker. In this example, the operation panel 104 may be implemented by a liquid crystal display (LCD) integrated with a touch panel. The touch panel may allow the user to make the selection or instruction according to the contents of the screen displayed by the LCD. The contents of the screen may be controlled by the main controller 111 via the operation panel controller 115. For example, the selection or instruction made by the user may be sent to the main controller 110 via the operation panel controller 115. The main controller 110 analyzes the user input, and changes the contents of the screen according to the user input via the operation panel controller 115.

[0071] The ADF 101 feeds an original document, which may be placed on a document tray of the ADF 101, to an image reading section of the scanner 102. The scanner 102 reads the original document into image data, which may be provided by the ADF 101 or provided on an exposure glass of the scanner 102.

In such case, a control program may be previously stored in the memory such as a ROM. Upon execution of the CPU, the control program being stored in the ROM may be loaded onto a RAM to cause the CPU to operate a plurality of functions describe above referring to any one of FIGS. 6 to 10.

[0125] Referring now to FIG. 31, operation of registering a plurality of apparatuses provided on the network N, performed by the session management server 3, is explained according to an example embodiment of the present invention. In this example, registration of the image forming apparatus 1 may be explained as a way of example since registration of the information processing apparatus 2 may be performed in a substantially similar manner.

[0126] When the image forming apparatus 1 is connected to the network N and the power is turned on, at S1, the I/O controller 113 of the image forming apparatus 1 sends a register request for registration to the session management server 3, for example, according to the SIP. When the register request is received, at S2, the session management server 3 may request the image forming apparatus 1 to send authentication information, for example, by sending a response to the image forming apparatus 1. At S3, the image forming apparatus 1 may send authentication information to the session management server 3.

[0127] At S4, the session management server 3 may store the authentication information when the authentication information includes an encrypted or decrypted key to be used for secured communication, together with other information such as the address information. Alternatively, at S4, the session management server 3 may determine whether the user at the image forming apparatus 1 is a registered user when the authentication information includes user authentication information such as a user ID and a password to generate a determination result. In such case, only when the determination result indicates that the user has been registered, the session management server 3 may accept the request sent from the image forming apparatus 1 and store information provided by the image forming apparatus 1.

[0128] At S5, the session management server 3 may further request the image forming apparatus 1 to send device information, for example, by sending a response to the image forming apparatus 1. At S6, the image forming apparatus 1 may send the device information to the session manager 3. When the device information is received, at S7, the session management server 3 may store the device information in the device information DB 304.

[0129] Further, at S8, the session management server 3 may send a selected portion of the device information to the image forming apparatus 1.

[0130] For example, the image forming apparatus 1 may store image processing function information obtained from the session management server 3 in the image processing information manager 152 (FIG. 29). Based on the image processing function information, the image forming apparatus 1 may generate a GUI that allows the user to input a user instruction for applying image processing. For example, the UI manager 153 of the I/O controller 113 (FIG. 29) may generate a screen providing a list of image processing functions available for use based on the image processing function information being obtained. The main controller 111 (FIG. 2) may cause the operation panel controller 115 to display the screen being generated through the operation panel 104, for example, when a user instruction is received.

[0131] The information processing apparatus 2 may be registered in a substantially similar manner as described above referring to S1 to S8. At S8, in addition to receiving image processing function information, the information processing apparatus 2 may receive device information regarding the image forming apparatus 1 from the device information DB 304, and store the device information in the printer information manager 253 (FIG. 4). Based on the device information obtainable from the printer information manager 253, the UI manager 254 of the information processing apparatus 1 may generate a screen providing a list of image forming apparatuses available for use. The main controller 201 (FIG. 3) may cause the user I/F 206 to display the screen being generated, for example, when a user instruction is received.

[0132] Further, any device information that is registered may be updated by the session management server 3 at any desired time. In one example, the session management server 3 may periodically request the image forming apparatus 1 or the information processing apparatus 2 to send device information. In another example, the session management server 3 may update the device information at the time when the image forming apparatus 1 or the information processing apparatus 2 sends presence information indicating that the image forming apparatus 1 or the information processing apparatus 2 is on line. In another example, the session management server 3 may update the device information at the time of receiving a request, such as a request for image processing or a request for image forming.

[0133] When the device information is updated, the UI manager 153 or 254 may update the screen according to the updated information. For example, a first screen is assumed to be generated based on the device information, which is obtained from the image processing management apparatus 6 at the time of registering. When a new device is added, for example, to the service providing server 5, the device information being obtained from the image processing management apparatus 6 may be updated to include device information including the new device that has been added. According to the updated information, the first screen is changed to a second screen that additionally includes at least a part of the device information regarding the new device.

[0134] Referring now to FIGS. 11 to 17, 25, 26, and 27, image processing operation and image forming operation performed by the image processing system of FIG. 1 are explained according to an example embodiment of the present invention. In this example, the information processing apparatus 2 generates a user request according to a user instruction received through the user I/F 206. Specifically, in this example, it is assumed that the user request includes an image processing request that requests for specific image processing to be applied to image data to generate processed image data, and an image forming request that instructs the image processing management apparatus 6 to output an image of the processed image data through the image forming apparatus 1.

[0135] When the user request is received from the information processing apparatus 2, the image processing management apparatus 6 analyzes the user request to determine how image processing and image forming should be performed by the image processing system of FIG. 1. Specifically, in this example described below referring to any one of FIGS. 11 to 17, 25, 26, and 27, the image processing management apparatus 6 determines whether the data format of the image data is interpretable by the image forming apparatus 1, which is designated to process the image forming request, to generate a determination result. Further, the image processing management apparatus 6 determines whether the specific image processing can be applied by the image forming apparatus 1 to generate a determination result. Based on the determination result, the image processing management apparatus 6 may generate an instruction, which specifies how a plurality of apparatuses on the network N including the image forming apparatus 1 and the information processing apparatus 2 should operate to process the user request.

[0136] FIG. 11 illustrates an example case in which the image processing management apparatus 6 of the image processing system of FIG. 1 determines that the image forming apparatus 1 is capable of interpreting the data format of the image data and applying the specific image processing to the image data to generate the processed image data.

[0137] At S1101, the information processing apparatus 2 receives a user instruction for printing image data after applying specific image processing. For example, when the user instruction is input by the user while the image data is displayed through the user I/F 206 by the application 202, the printing controller 205 (FIG. 3) may be executed. The printing controller 205 may display the user via the user I/F 206 a screen for setting various information regarding image processing and image forming of the image data, which may be generated by the UI manager 255 (FIG. 4) based on the image processing function information or the printer information described above referring to FIGS. 4 and 5.

[0138] At S1102, when the information regarding image processing and image forming of the image data is set by the user and an instruction for printing the image data after applying image processing is confirmed by the user, the printing controller 205 may generate an image processing request for applying specific image processing and an image forming request for forming an image, which may be collectively referred to as a user request. The user request includes information regarding image processing and image forming of the image data. For example, as illustrated in FIG. 12, the user request includes header information ("HEADER"), image data information regarding the image data to be processed ("IMAGE DATA"), image processing information indicating specific image processing to be applied to the image data ("IMAGE PROCESSING"), printer information regarding the specific image forming apparatus to form an image of the processed image data ("PRINTER"), or encryption key information to be used for secured communication ("KEY").

[0139] At S1103, the main controller 201 of the information processing apparatus 2 sends the user request to the session management server 3 through the network I/F 204.

[0140] When the session manager 302 of the session management server 3 receives the user request from the information processing apparatus 2 through the network I/F 303, at S1104, the service manager 306 of the session management server 3 (FIG. 6) analyzes the user request to generate a determination result indicating how the image processing system of FIG. 1 should process the user request. For example, the service manager 306 may obtain the image data information and the printer information respectively from the user request, and determine whether the image data being selected has a data format interpretable by the image forming apparatus 1 specified by the printer information. In this example, when the image processor 114 of the image forming apparatus 1 is capable of interpreting the data format of the image data and generating print data to be processed by the printer engine 106, it is assumed that the image data is interpretable by the image forming apparatus 1. In this example, the service manager 306 may determine whether the data format is interpretable by the image forming apparatus 1 by referring to the data format information stored in the device information DB 304 (FIG. 7).

[0141] Additionally, the service manager 306 may obtain the image processing information and the printer information respectively from the user request, and determine whether the image processing specified by the image processing information can be applied by the image forming apparatus 1 specified by the printer information. In this example, when the image processor 114 of the image forming apparatus 1 has the image processing function that corresponds to the image processing specified by the image processing information, it is assumed that the image processing can be applied by the image forming apparatus 1. For example, when the image processing information indicates the thumbnail printing function described above referring to FIG. 5 is to be applied, the service manager 306 of the session management server 3 determines whether the image forming apparatus 1 has the thumbnail printing function. In this example, the service manager 306 may determine whether the image processing can be applied by the image forming apparatus 1, by referring to the image processing function information stored in the device information DB 304 (FIG. 7).

[0142] In this example, it is assumed that the determination result generated by the service manager 306 indicates that the data format is interpretable by the image forming apparatus 1 and the image processing can be applied by the image forming apparatus 1.

[0143] At S1105, the session manager 302 sends an instruction generated based on the determination result obtained at S1104 to the information processing apparatus 2. The instruction may indicate that the user request can be processed by the image forming apparatus 1.

[0144] At S1106, the session manager 302 sends a session start instruction to the image forming apparatus 1 through the network I/F 303, which instructs the image forming apparatus 1 to start a session with the information processing apparatus 2. The session start instruction may include address information of the information processing apparatus 2 and encryption key information obtained from the information processing apparatus 2, which are respectively stored in the device information DB 304.

[0145] Further, in this example, when the session start instruction is received from the session management server 3, the image forming apparatus 1 opens an input/output port for data channel, which is kept closed.

[0146] At S1107, the image forming apparatus 1 sends a session start request to the information processing apparatus 2 through the network I/F 108, which requests the information processing apparatus 2 to start a session with the image forming apparatus 1. In this example, the image forming apparatus 1 may communicate with the information processing apparatus 1 using the encryption key information. Further, the session start request may include address information of the image forming apparatus 1 and authentication information of the image forming apparatus 1.

[0147] When the information processing apparatus 2 receives the session start request, at S1108, the information processing apparatus 2 sends a session start response to the image forming apparatus 1 to establish a session with the image forming apparatus 1. In this example, the information processing apparatus 2 may communicate with the image forming apparatus 1 using the encryption key information.

[0148] When the session is established between the information processing apparatus 2 and the image forming apparatus 1 at S1108, at S1109, the printing controller 205 of the information processing apparatus 2 sends the image data to be processed, and the image processing information that may be generated at S1102, to the image forming apparatus 1 through the network I/F 204.

[0149] When the image forming apparatus 1 receives the image data and the image processing information, at S1110, the image processor 114 of the image forming apparatus 1 applies image processing specified by the image processing information to generate processed image data. The engine controller 112 may cause the printer engine 106 to form an image of the processed image data, and the operation ends.

[0150] In this example, before establishing the session at S1108, for example, at S1103, S1105, S1106, S1107, and S1108, communication between at least two of the information processing apparatus 2, the session management server 3, and the image forming apparatus 1 may be performed through a signaling channel, for example, using the signaling protocol such as the SIP. After establishing the session at S1108, for example, at S1109, communication between the information processing apparatus 2 and the image forming apparatus 1 may be performed through a data channel, for example, using the HTTP. Further, in this example, any desired type of secured communication may be implemented.

[0151] The operation of FIG. 11 may be performed in various other ways. For example, at S1103, the information processing apparatus 2 may send the image data to be processed together with the user request to the session management server 3. In such case, the user request does not have to be provided with the image data information since the session management server 3 is capable of determining whether the data format of the image data is interpretable by the image forming apparatus 1, by analyzing the image data file.

[0152] In another example, instead of causing the information processing apparatus 2 to send the image data or the image processing information to the image forming apparatus 1 at S1109, the session management server 3 may send the image data or the image processing information to the image forming apparatus 1. In such case, the session management server 3 may send a notice to the information processing apparatus 2 that the user request is processed by the image forming apparatus 1. Further, the session management server 3 requests the image forming apparatus 1 to start a session with the session management server 3.

[0153] In another example, at S1104, the session management server 3 may additionally determine whether the image forming apparatus 1 has enough resource to process the image forming request. For example, when the image forming request is received, the session management server 3 may obtain printer supply information from the image forming apparatus 1, and analyze the printer supply information to determine whether the image forming apparatus 1 is capable of forming an image. Alternatively, the printer supply information may be obtained from the device information DB 304 at any desired time. The printer supply information may include information regarding the printer supply, such as the amount of toner remained in a toner container or the remaining number of recording sheets provided in the document tray 105, which may be obtained by a detector provided by the document tray 105 or the printer engine 106. When the printer supply information indicates that there is not enough resource to process the image forming request, the session management server 3 may send a notice to the information processing apparatus 2 without sending the session start instruction to the image forming apparatus 1. When the notice is received, the user at the information processing apparatus 2 may replace the toner container or place additional recording sheets to the documents tray 105, depending on the notice being received. When the session management server 3 receives a notice from the image forming apparatus 1 that the printer supply is replenished, the session management server 3 may proceed to S1106 to send the session start instruction to the image forming apparatus 1. Instead of sending the notice to the information processing apparatus 2 in case when the shortage of the printer supply is detected, the session management server 3 may send a notice to an information processing apparatus where the administrator is logged on or an image forming processing apparatus of any other person who may be responsible for managing the image forming apparatus 1.

[0154] In another example, at S1101, the user may request the information processing apparatus 2 to print image data, which is stored in the data storage 203 (FIG. 3), after applying image processing. In such case, the application 202 does not have to be executed.

[0155] Alternatively, at S1101, the user may request the information processing apparatus 2 to print image data, which is stored at any desired location on the network N. In such case, the printing controller 205 does not have to be executed as long as the web browser of the application 202 is executed to receive various information regarding image processing or image forming, from the other apparatus providing the web service to the information processing apparatus 2.

[0156] FIG. 13 illustrates an example case in which the image processing management apparatus 6 of the image processing system of FIG. 1 determines that the image forming apparatus 1 is not capable of interpreting the data format of the image data or not capable of applying the specific image processing to the image data. Further, in this example, it is assumed that the image data to be processed is sent to the session management server 3 together with the user request. Further, in this example, it is assumed that one device of the service providing server 5 is found to be capable of applying the data conversion or the specific image processing.

[0157] At S1301, the information processing apparatus 1 receives a user instruction for printing image data after applying image processing, generates a user request including an image processing request and an image forming request, and sends the user request to the session management server 3, in a substantially similar manner as described above referring to S1101, S1102, and S1103 of FIG. 11. In this example, as described above, it is assumed that the image data to be processed is sent together with the user request.

[0158] At S1302, the service manager 306 of the session management server 3 analyzes the user request to generate a determination result indicating how the image processing system of FIG. 1 should process the user request, in a substantially similar manner as described above referring to S1104 of FIG. 11. In this example, it is assumed that the determination result indicates that the data format is not interpretable by the image forming apparatus 1 or the specific image processing cannot be applied by the image forming apparatus 1.

[0159] At S1303, the session manager 302 sends the image data obtained at S1301 to the service management server 4 through the network I/F 303. Together with the image data, the session manager 302 sends an instruction generated by the service manager 306 based on the determination result obtained at S1302. In this example, the instruction may request the service management server 4 to perform data conversion to convert the data format of the image data to a data format that is interpretable by the image forming apparatus 1, when the determination result at S1302 indicates that the data format is not interpretable by the image forming apparatus 1. Additionally or alternatively, the instruction may request the service management server 4 to apply the specific image processing, when the determination result at S1302 indicates that the specific image processing cannot be applied by the image forming apparatus 1.

[0160] When the service management server 4 receives the instruction and the image data to be processed through the network I/F 403, at S1304, the service management server 4 may search through the service providing server 5 to find a device that is capable of applying data conversion specified by the instruction. For example, under control of the main controller 401, the service manager 402 may analyze the instruction, and search for a device of the service providing server 5 that is capable of converting the data format to the data format interpretable by the image forming apparatus 1 by referring to the service provider information DB 404. Additionally or alternatively, the service manager 402 may analyze the instruction, and search through the service providing server 5 to obtain a device that is capable of applying the specific image processing to the image data.

[0161] When the service manager 402 finds the service providing server 5 capable of applying data conversion or image processing, at S1305, the main controller 401 sends the image data to be processed to the service providing server 5 being searched through the network I/F 403, together with the instruction for applying specific data conversion or image processing.

[0162] When the image data and the instruction are received by the service providing server 5 through the network I/F 503, at S1306, under control of the main controller 501, the service provider 502 may apply data conversion to the image data according to the instruction. Additionally or alternatively, the service provider 502 may apply specific image processing to the image data according to the instruction. As a result, the processed image data having the data format interpretable by the image forming apparatus 1 is generated.

[0163] At S1307, the main controller 501 sends the processed image data generated at S1306 to the session management server 3 through the network I/F 503.

[0164] When the processed image data is received by the session management server 3 through the network I/F 303, at S1308, the main controller 301 sends the processed image data to the image forming apparatus 1 through the network I/F 303 together with an instruction to print the processed image data.

[0165] At S1309, the main controller 111 of the image forming apparatus 1 causes the image processor 114 to apply further image processing to the processed image data to generate print data. The main controller 111 further causes the engine controller 112 to print the print data, and the operation ends.

[0166] FIG. 15 illustrates an example case in which the image processing management apparatus 6 of the image processing system of FIG. 1 determines that the image forming apparatus 1 is not capable of interpreting the data format of the image data or not capable of applying the specific image processing to the image data. Further, in this example, it is assumed that the user request is sent to the session management server 3 without the image data to be processed. Further, in this example, one device of the service providing server 5 is found to be capable of applying the data conversion or the specific image processing.

[0167] At S1501, the information processing apparatus 1 receives a user instruction for printing image data after applying image processing, generates a user request including an image processing request and an image forming request, and sends the user request to the session management server 3, in a substantially similar manner as described above referring to S1101, S1102, and S1103 of FIG. 11.

[0168] At S1502, the service manager 306 of the session management server 3 analyzes the user request to generate a determination result indicating how the image processing system of FIG. 1 should process the user request, in a substantially similar manner as described above referring to S1104 of FIG. 11. In this example, it is assumed that the determination result indicates that the data format is not interpretable by the image forming apparatus 1 or the specific image processing cannot be applied by the image forming apparatus 1.

[0169] At S1503, the session manager 302 sends an instruction generated based on the determination result obtained at S1502 to the service management server 4 through the network I/F 303 in a substantially similar manner as described above referring to S1303 of FIG. 13, however, without the image data to be processed.

[0170] When the service management server 4 receives the instruction through the network I/F 403, at S1504, the service management server 4 may search for the service providing server 5 capable of applying data conversion specified by the instruction or applying specific image processing specified by the instruction, in a substantially similar manner as described above referring to S1304 of FIG. 13.

[0171] When the service manager 402 finds the service providing server 5 capable of applying data conversion or image processing, at S1505, the main controller 401 of the service management server 4 sends a search result specifying the service providing server 5 capable of applying data conversion or image processing to the session management server 3 through the network I/F 403. The search result may include information regarding the service providing server 5 being found, such as address information or authentication information.

[0172] When the search result is received, at S1506, the session management server 3 sends an instruction generated based on the determination result of S1502 and the search result received from the service management server 4, to the information processing apparatus 2. For example, the instruction may indicate that the specific image processing cannot be applied by the image forming apparatus 2 but can be applied by the service providing server 5. The instruction may further request the information processing apparatus 2 to start a session with the service providing server 5. The instruction may further include the address information or the authentication information of the service providing server 5, which may be obtainable from the search result.

[0173] At S1507, the session management server 3 sends a session start instruction to the service providing server 5 being searched to request the service providing server 5 to start a session with the information processing apparatus 2. The instruction may include address information or authentication information of the information processing apparatus 2.

[0174] At S1508 and S1509, the information processing apparatus 2 and the service providing server 5 establish a session. In this example, the session may be established using the authentication information.

[0175] At S1510, the information processing apparatus 2 sends the image data to be processed and the image processing information to the service providing server 5.

[0176] When the image data and the image processing information are received, at S1511, the service providing server 5 applies the specific image processing specified by the image processing information of the image processing request to the image data to generate the processed image data.

[0177] At S1512, the service providing server 5 sends the processed image data to the session management server 3.

[0178] At S1513, the session management server 3 sends the processed image data to the image forming apparatus 1, together with an instruction to print the processed image data.

[0179] At S1514, the image forming apparatus 1 prints the image data in a substantially similar manner as described above referring to S1309 of FIG. 13, and the operation ends.

[0180] The operation of FIG. 13 or 15 may be performed in various other ways. For example, the data conversion or the specific image processing may be applied by more than one device of the service providing server 5. In one example, the data conversion may be applied by a first device of the service providing server 5, while the specific image processing may be applied by a second device of the service providing server 5. In another example, the specific image processing, which may be broken down into a plurality of image processing operations, may be applied by a plurality of devices of the service providing server 5.

[0181] In such case, as illustrated in FIG. 32, the service management server 4 may be additionally provided with a processing order manager 405. The processing order manager 405 may determine an order of applying the plurality of image processing operations to generate a processing order determination result, for example, when the image processing is applied by a plurality of devices of the service providing server 5 each applying at least one of the plurality of image processing operations. The service manager 402 of the service management server 4 may generate an instruction based on the processing order determination result, and send the instruction to one device of the service providing server 5 according to the processing order determination result, to cause the service providing server 5 to apply the plurality of image processing operations in the order specified by the processing order determination result.

[0182] Referring now to FIG. 14, operation of managing the image processing system of FIG. 1, performed by the session management server 3, is explained according to an example embodiment of the present invention.

[0183] At S1401, the session manger 302 receives a user request from the information processing apparatus 2.

[0184] At S1402, the service manager 306 analyzes the user request to obtain printer information to identify a printer designated by the user to perform the image forming request. In this example, the image forming apparatus 1 is assumed to be designated.

[0185] At S1403, the service manager 306 obtains status information or supply information of the image forming apparatus 1, for example, by referring to the device information stored in the device information DB 304 to determine whether the image forming apparatus 1 is capable of performing image formation to generate a determination result. When the determination result at S1403 indicates that the image forming apparatus 1 is not capable of performing image formation ("NO" at S1403), the operation proceeds to S1404. When the determination result at S1403 indicates that the image forming apparatus 1 is capable of performing image formation ("YES" at S1403), the operation proceeds to S1405.

[0186] At S1404, the session manager 302 sends a notice to the information processing apparatus 2, which reports that the image forming apparatus 1 is not capable of performing image formation, through the network I/F 303. The notice may request the user to turn on the image forming apparatus 1 or replenish the printer supply of the image forming apparatus 1 based on the determination result obtained at S1403. After S1404, the operation returns to S1403.

[0187] At S1405, the service manager 306 analyzes the user request to obtain the data format of the image data to be processed and image processing to be applied to the image data.

[0188] At S1406, the service manager 306 determines whether the data format of the image data obtained at S1405 is interpretable by the image forming apparatus 1 and whether image processing obtained at S1405 can be applied by the image forming apparatus 1.

[0189] When it is determined that the data format is interpretable by the image forming apparatus 1 and the image processing can be applied by the image forming apparatus 1 ("YES" at S1406), the operation proceeds to S1407. When it is determined that the data format is not interpretable by the image forming apparatus 1 or the image processing cannot be applied by the image forming apparatus 1, the operation proceeds to S1409.

[0190] At S1407, the session manager 302 sends a session start instruction to the image forming apparatus 1 through the network I/F 303 to request the image forming apparatus 1 to start a session with the information processing apparatus 2.

[0191] At S1409, the service manager 306 may generate an instruction based on the determination result obtained at S1406. In this example, the instruction being generated requests the service management server 4 to apply data conversion that converts the data format of the image data to be processed to the data format interpretable by the image forming apparatus 1 when the determination result at S1406 indicates that the data format of the image data to be processed is not interpretable by the image forming apparatus 1. Alternatively or additionally, the instruction being generated requests the service management server 4 to apply image processing specified by the image processing information of the user request when the determination result at S1406 indicates that the image processing cannot be applied by the image forming apparatus 1. The session manager 302 may send the instruction to the service management server 4 through the network I/F 303 together with the image data to be processed.

[0192] At S1410, the session manager 302 receives the image data being processed by the service providing server 5, and sends the processed image data to the image forming apparatus 1.

[0193] At S1408, the session manager 302 sends an instruction generated based on the determination result obtained at S1406 to the information processing apparatus 2 through the network I/F 303, and the operation ends. In this example, when the determination result obtained at S1406 indicates that the image forming apparatus 1 is capable of interpreting the data format and applying image processing, the instruction being generated may request the information processing apparatus 2 to send the image data to be processed and the image processing information to the image forming apparatus 1. When the determination result obtained at S1406 indicates that the image forming apparatus 1 is not capable of interpreting the data format or applying image processing, the instruction being generated may notify the information processing apparatus 2 that the image data is being printed by the image forming apparatus 1 after being processed by the service providing server 5.

[0194] As described above referring to any one of FIGS. 13 to 15, the information processing apparatus 2 does not have to convert the data format of the image data to be the data format interpretable by the image forming apparatus 1, before sending the image data to the image forming apparatus 1. Since the information processing apparatus 2 does not need to perform data conversion, or the information processing apparatus 2 does not have to determine whether any data conversion is necessary, the printing controller 205 (FIG. 3) does not have to be provided with the function of performing data conversion. Accordingly, the printing controller 205 does not have to be upgraded or re-designed even when the image forming apparatus 1 is replaced with another image forming apparatus or even when the image processing system of FIG. 1 is additionally provided with one or more image forming apparatuses.

[0195] Further, the user is capable of requesting specific image processing, even when neither one of the image forming apparatus 1 and the information processing apparatus 2 is capable of applying the specific image processing. As long as at least one device that is capable of applying the specific image processing is provided on the network N, the user may request the specific image processing.

[0196] Further, even when image processing that the user desires to perform is not provided by the image processing system of FIG. 1, the system may be changed so as to provide such image processing function, for example, by adding the service providing server 5 capable of performing the requested image processing to the network B of the service provider. In such case, the user does not have to add another apparatus to the network A or does not have to change the settings of any apparatus provided on the network A.

[0197] Further, as described above referring to FIG. 13 and FIG. 15, for example, the information processing apparatus 2 does not have to send the image data to be processed until when it receives an instruction to send the image data to an apparatus specified by the image processing management apparatus 6, from the image processing management apparatus 6. This may reduce the overall network load of the system or the overall processing load of the apparatus on the network N. Further, since the image data is sent after the session is established, that is, preferably after the client and server apparatuses are authenticated, the image data may be protected from the access or attack from the unauthorized user.

[0198] FIG. 25 illustrates an example case in which the image processing management apparatus 6 of the image processing system of FIG. 1 determines that the image forming apparatus 1 is capable of interpreting the data format of the image data but not capable of applying the image processing to the image data. Further, the specific image processing may include a plurality of image processing operations. Further, in this example, it is assumed that a plurality of devices of the service providing server 5 are found to be capable of together applying the plurality of image processing operations of the specific image processing. Further, as described above referring to FIG. 32, the image processing management apparatus 6 is provided with the processing order manager 405, which determines an order of applying the plurality of image processing operations.

[0199] At S2501, the information processing apparatus 2 receives a user instruction for printing image data after applying image processing, generates a user request including an image processing request and an image forming request, and sends the user request to the session management server 3. In this example, the image data to be processed is not sent.

[0200] At S2502, the service manager 306 of the session management server 3 analyzes the user request to generate a determination result indicating how the image processing system of FIG. 1 should process the user request. In this example, it is assumed that the determination result indicates that the data format is interpretable by the image forming apparatus 1 but the specific image processing cannot be applied by the image forming apparatus 1.

[0201] At S2503, the session manager 302 sends an instruction generated based on the determination result obtained at S2502 to the service management server 4 through the network I/F 303. The instruction may request the service management server 4 to apply a plurality of image processing operations of the specific image processing.

[0202] When the service management server 4 receives the instruction through the network I/F 403, at S2504, the service management server 4 may search for the service providing server 5 capable of applying specific image processing specified by the instruction. In this example, the search result indicates that a plurality of devices of the service providing server 5 are capable of together applying the plurality of image processing operations of the specific image processing.

[0203] Further, at S2504, the processing order manager 405 (FIG. 32) of the service management server 4 determines an order of applying the plurality of image processing operations to generate a processing order determination result. The service manager 402 of the service management server 4 generates an instruction based on the processing order determination result. Specifically, in this example, the instruction may include route information regarding a route of which the image data to be processed is transferred from device to device of the service providing server 5. The instruction may further include address information or authentication information of each device of the service providing server 5, which is found to be capable of applying at least one of the plurality of image processing operations.

[0204] At S2505, the service management server 4 sends the instruction being generated at S2504 to the session management server 3.

[0205] When the instruction is received from the service management server 4, at S2506, the session management server 3 sends an instruction to the information processing apparatus 2. In this example, the instruction at least includes the route information.

[0206] At S2507, the session management server 3 sends a session start instruction to a first device of the service providing server 5, which requests the first device to start a session with the information processing apparatus 2. In this example, the first device is the device, which is determined by the service management server 4 to firstly apply the image processing operation.

[0207] At S2508 and S2509, the information processing apparatus 2 and the first device of the service providing server 5 establish a session. In this example, the session may be established using the authentication information.

[0208] At S2510, the information processing apparatus 2 sends the image data to be processed and an instruction including the image processing information, to the first device of the service providing server 5. The instruction further includes the route information regarding the route of which the image data to be processed is transferred from device to device of the service providing server 5.

[0209] When the image data and the instruction are received, at S2511, the first device of the service providing server 5 applies the specific image processing specified by the instruction to the image data to generate the processed image data.

[0210] At S2511, after applying image processing, the first device of the service providing server 5 may refer to the route information to obtain information regarding a second device of the service providing server 5 that is determined to secondly apply the image processing operation. The first device of the service providing server 5 sends the processed image data and the instruction including the image processing information and the route information, to the second device of the service providing server 5. In this example, the first device of the service providing server 5 and the second device of the service providing server 5 establish a session under control of the session management server 3.

[0211] When the image data and the instruction are received, at S2512, the second device of the service providing server 5 applies the image processing according to the instruction. After applying image processing, the second device of the service providing server 5 may refer to the route information to obtain information regarding a third device of the service providing server 5 that is determined to subsequently apply the image processing operation, if any. When there is the third device to apply further image processing, the second device of the service providing server 5 sends the image data and the instruction to the third device of the service providing server 5. This process described above referring to S2511 or S2512 may be repeated until all image processing operations are processed by all devices being found.

[0212] When all image processing operations are processed, at S2513, the device of the service providing server 5 sends the processed image data to the image forming apparatus 1. In this example, the device of the service providing server 5 and the image forming apparatus 1 may establish a session under control of the session management server 3. After establishing the session, the image data is transferred from the service providing server 5 to the image forming apparatus 1 through a data channel.

[0213] When the processed image data is received, at S2514, the image forming apparatus 1 prints the processed image data, and the operation ends.

[0214] Referring now to FIG. 26, operation of managing image processing performed by the service management server 3 based on the route information, is explained according to an example embodiment of the present invention. For the descriptive purpose, in this example, it is assumed that the first device 5a of the service providing server 5 ("service providing server 5a") and the second device 5b of the service providing server 5 ("service providing server 5b") are assumed to apply the image processing to generate the processed image data. Further, in this example, the route information indicates that the image data should be transferred in the order of the first device 5a and the second device 5b. The operation of FIG. 26 may correspond to S2510 to S2513 of FIG. 25.

[0215] At 2601, the first device 5a of the service providing server 5 receives the image data and the instruction, which are sent from the information processing apparatus 1 at S2510 of FIG. 25. The instruction includes the image processing information and the route information.

[0216] At S2602, the first device 5a of the service providing server 5 applies image processing to the image data according to the image processing information of the instruction.

[0217] At S2603, the first device 5a of the service providing server 5 refers to the route information, and sends a session start request to the session management server 3, which requests starting of a session with the second device 5a of the service providing server 5 to which the processed image data and the instruction should be sent.

[0218] When the session start request is received, at S2604, the session management server 3 sends a session start instruction to the second device 5b of the service providing server 5, which requests starting of a session with the first device 5a.

[0219] At S2605 and S2606, the first device 5a and the second device 5b of the service providing server 5 establish a session.

[0220] When the session is established, at S2607, the first device 5a of the service providing server 5 sends the processed image data and the instruction to the second device 5b of the service providing server 5.

[0221] When the image data and the instruction are received, at S2608, the second device 5b of the service providing server 5 applies the image processing to the image data according to the image processing information of the instruction.

[0222] At S2609, the second device 5b of the service providing server 5 refers to the route information, and sends a session start request to the session management server 3, which requests starting of a session with the image forming apparatus 1.

[0223] When the session start request is received, at S2610, the session management server 3 sends a session start instruction to the image forming apparatus 1.

[0224] At S2611, the second device 5b of the service providing server 5 establishes a session with the image forming apparatus 1.

[0225] When the session is established, at S2612, the second device 5b of the service providing server 5 sends the processed image data to the image forming apparatus 1.

[0226] The operation of FIG. 26 may be performed in various other ways. For example, after completing image processing, for example, at S2603 or S2609, the service providing server 5 may send a notice to the session management server 3, which reports completion of the image processing. When the notice is received, the session management server 3 may refer to the route information, and send an instruction to the device that is determined to subsequently apply image processing to cause the device to apply image processing.

[0227] Referring to FIG. 27, operation of managing image processing performed by the service management server 3 based on the route information, is explained according to an example embodiment of the present invention. For the descriptive purpose, in this example, it is assumed that the first device 5a of the service providing server 5 and the second device 5b of the service providing server 5 are assumed to apply the image processing to generate the processed image data. Further, in this example, the route information indicates that the image data should be transferred in the order of the first device 5a and the second device 5b. The operation of FIG. 27 may correspond to S2506 to S2514 of FIG. 25.

[0228] At S2701, the session management server 3 receives the route information from the service management server 4.

[0229] At S2702, the session management server 3 generates an instruction based on the route information, and sends the instruction to the first device 5a of the service providing server 5. In this example, the instruction requests the first device 5a of the service providing server 5 to obtain the image data to be processed and the image processing information from the information processing apparatus 2. Specifically, in this example, the instruction includes information regarding the location where the image data and the image processing information are stored, which may be expressed as URL.

[0230] When the instruction is received from the session service manager 3, at S2703, the first device 5a of the service providing server 5 obtains the image data and the image processing information from the information processing apparatus 2 based on the instruction.

[0231] When the image data and the image processing information are obtained, at S2704, the first device 5a of the service providing server 5 applies the image processing specified by the image processing information to the image data.

[0232] At S2705, the first device 5a of the service providing server 5 sends a notice to the session management server 3 that image processing is completed.

[0233] When the notice is received from the first device 5a of the service providing server 5, at S2706, the session management server 3 refers to the route information, and sends an instruction to the second device 5b of the service providing server 5. In this example, the instruction may request the second device 5b of the service providing server 5 to obtain the image data to be processed and the image processing information from the first device 5a of the service providing server 5. Specifically, in this example, the instruction includes information regarding the location where the image data and the image processing information are stored, which may be expressed as URL.

[0234] When the instruction is received, at S2707, the second device 5b of the service providing server 5 sends a request to the first device 5a of the service providing server 5 for the image data and the image processing information.

[0235] When the request is received, at S2708, the first device 5a of the service providing server 5 sends the image data and the image processing information.

[0236] When the image data and the image processing information are obtained, at S2709, the second device 5b of the service providing server 5 applies the image processing to the image data according to the image processing information.

[0237] At S2710, the second device 5b of the service providing server 5 sends a notice to the session management server 3 that the image processing is completed.

[0238] At S2711, the session management server 3 refers to the route information, and sends an instruction to the image forming apparatus 1 that is designated to output the processed image data. The instruction may request the image forming apparatus 1 to obtain the processed image data from the second device 5b of the service providing server 5. The instruction may include information regarding the location where the processed image data is stored.

[0239] At S2712, the image forming apparatus 1 sends a request to the second device 5b of the service providing server 5, which requests for the processed image data.

[0240] At S2713, the second device 5b of the service providing server 5 sends the processed image data to the image forming apparatus 1.

[0241] At S2714, the image forming apparatus 1 prints the processed image data, and the operation ends.

[0242] In this example described above referring to FIG. 27, any information such as the image data may be transferred while being encrypted. For example, at S2704, the first device 5a of the service providing server 5 may encrypt the processed image data with the encrypted key. When sending the notice at S2705, the first device 5a of the service providing server 5 may send the encrypted key information. Further, at S2706, the session management server 3 sends the encrypted key information being obtained from the first device 5a of the service providing server 5, to the second device 5b of the service providing server 5. At S2707 and 2708, the second device 5b of the service providing server 5 obtains the image data using the encrypted key information being obtained from the session managements server 3. For improved security, S2703, S2712, or S2713 may be performed in a substantially similar manner using the encrypted key information.

[0243] As described above referring to FIG. 1, the image processing management apparatus 6 may be implemented in various other ways. Referring now to FIGS. 16 and 17, an example case in which the image processing management apparatus 6 is implemented by the session management server 3 shown in FIG. 6 is explained. However, in this example, it is assumed that the device information DB 304 (FIG. 6) additionally stores device information regarding the service providing server 5, such as the device information illustrated in FIG. 9.

[0244] FIG. 16 illustrates an example case in which the image processing management apparatus 6 determines that the image forming apparatus 1 is not capable of interpreting the data format of the image data and not capable of applying the image processing to the image data. Further, in this example, it is assumed that a first device 5a (the "service providing server 5a") and a second device 5b (the "service providing server 5b") of the service providing server 5 are found to be capable of respectively applying the data conversion and the specific image processing.

[0245] At S1601, the information processing apparatus 2 receives a user instruction for printing image data after applying image processing, generates a user request including an image processing request and an image forming request, and sends the user request to the session management server 3, in a substantially similar manner as described above referring to S1101, S1102, and S1103 of FIG. 11. In this example, it is assumed that the image data to be processed is sent together with the user request.

[0246] At S1602, the service manager 306 of the session management server 3 analyzes the user request to generate a determination result indicating how the image processing system of FIG. 1 should process the user request, in a substantially similar manner as described above referring to S1104 of FIG. 11. In this example, it is assumed that the determination result indicates that the data format is not interpretable by the image forming apparatus 1 and the specific image processing cannot be applied by the image forming apparatus 1.

[0247] At S1603, the service manager 306 searches through the service providing server 5 to find a device that is capable of applying data conversion and a device that is capable of applying image processing, in a substantially similar manner as described above referring to S1304 of FIG. 13. In this example, the search result indicates that the first device 5a of the service providing server 5 is capable of applying data conversion, and the second device 5b of the service providing server 5 is capable of applying image processing. Based on the search result, the service manager 306 may generate an instruction, which requests the service providing server 5 to apply the data conversion and the image processing. The instruction may include information regarding the device being found, such as the first device 5a and the second device 5b of the service providing server 5. The instruction may additionally include route information regarding the order in which the image data and the instruction are transferred from device to device. The route information may be previously determined by default. Alternatively, the route information may be determined based on the status information of the service providing server 5, which may be obtainable from the device information when searching through the service providing server 5.

[0248] Further, at S1603, the service manager 306 sends the image data to be processed to the first device 5a of the service providing server 5, together with the instruction being generated based on the search result. In this example, the service manager 306 may arbitrarily determine a device to which the image data and the instruction are sent. Alternatively, the device to which the image data and the instruction are sent may be previously set based on the route information.

[0249] At S1604, the first device 5a of the service providing server 5 applies the data conversion to the image data according to the instruction.

[0250] At S1605, the first device 5a of the service providing server 5 sends the processed image data and the instruction to the second device 5a of the service providing server 5. The instruction may be updated by the first device 5a of the service providing server 5 so as to indicate that the data conversion is completed or the image data is processed by the first device 5a of the service providing server 5.

[0251] At S1606, the second device 5b of the service providing server 5 applies the image processing to the processed image data being received from the first device 5a of the service providing server 5 according to the instruction.

[0252] At S1607, the second device 5b of the service providing server 5 sends the processed image data to the session management server 3. In order to determine whether to send the processed image data to the session management server 3, the second device 5b of the service providing server 5 may determine whether the data conversion and the image processing, which are specified by the instruction, are completed by referring to the contents of the instruction that may be updated as it is transferred from device to device of the service providing server 5.

[0253] At S1608, the session management server 3 sends the processed image data to the image forming apparatus 1.

[0254] At S1609, the image forming apparatus 1 prints the image data, and the operation ends.

[0255] FIG. 17 illustrates an example case in which the image processing management apparatus 6 determines that the image forming apparatus 1 is not capable of interpreting the data format of the image data and not capable of applying the image processing to the image data. Further, in this example, it is assumed that the second device 5b (the "service providing server 5b") of the service providing server 5 is found to be capable of respectively applying the data conversion and the specific image processing.

[0256] S1701 to S1703 are performed in a substantially similar manner as described above referring to S1601 to S1603. However, in this example, the instruction being generated at S1703 is provided with the data format information and the image processing information, but not provided with information regarding the search result or information generated based on the search result. Further, in this example, it is assumed that the image data and the instruction are sent from device to device of the service providing server 5 until all image processing operations are performed on the image data. The route of which the image data and instruction are transferred may be set by default or determined based on the status information of each device of the service providing server 5.

[0257] When the image data and the instruction are received, at S1704, the first device 5a of the service providing server 5 determines whether it is necessary to apply data conversion or image processing to the image data, for example, by comparing the image processing function that the first device 5a of the service providing server 5 can offer with the image processing specified by the instruction. In this example, it is assumed that there is no data conversion or image processing that the first device 5a of the service providing server 5 can provide.

[0258] In such case, at S1705, the first device 5a of the service providing server 5 sends the image data, without processing, to the second device 5b of the service providing server 5 together with the instruction. The instruction may be updated so as to indicate that the image data and the instruction are sent to the first device 5a of the service providing server 5 or no image processing is applied to the image data.

[0259] When the image data and the instruction are received, at S1706, the second device 5b of the service providing server 5 determines whether it is necessary to apply data conversion or image processing to the image data, for example, by comparing the image processing function that the second device 5b of the service providing server 5 can offer with the image processing specified by the instruction. In this example, it is assumed that the data conversion and the image processing specified by the instruction can be applied by the second device 5b of the service providing server 5.

[0260] At S1707, the second device 5b of the service providing server 5 applies the data conversion and the image processing to the image data being received from the first device 5a of the service providing server 5 to generate the processed image data.

[0261] At S1708, the second device 5b of the service providing server 5 sends the processed image data to the session management server 3. In order to determine whether to send the processed image data to the session management server 3, the second device 5b of the service providing server 5 may determine whether the data conversion and the image processing, which are specified by the instruction, are completed by referring to the contents of the instruction that may be updated as it is transferred from device to device of the service providing server 5.

[0262] At S1709, the session management server 3 sends the processed image data to the image forming apparatus 1.

[0263] At S1710, the image forming apparatus 1 prints the image data, and the operation ends.

[0264] The image processing operation described above referring to FIGS. 11 to 17, 25, 26, and 27 may be performed in various other ways.

[0265] For example, rather than determining whether the image forming apparatus 1 is capable of applying data conversion or image processing, the session management server 3 may pass the user request, which may be provided with the image data, to the service management server 4. In such case, the service manager 306 does not have to be provided.

[0266] In another example, the image forming request does not have to be provided with the printer information, for example, when the user instruction does not specify the image forming apparatus. In such case, when the user request is received from the information processing apparatus 2, the session management server 3 may select the image forming apparatus by default or based on the other information of the user request. For example, the session management server 3 may obtain the data format information from the user request, or obtain the data format information from the image data file. Based on the data format, the session management server 3 may select one of the image forming apparatuses, for example, by referring to the device information DB 304.

[0267] In such case, when a plurality of image forming apparatuses are available, the session management server 3 may request the user at the information processing apparatus 2 to select one of the plurality of image forming apparatuses. For example, at least one of the session management server 3, the service management server 4, and the service providing server 5 may send the processed image data to which the image processing is applied to the information processing apparatus 2. The information processing apparatus 2 may send the selected one of the image forming apparatuses to complete image formation.

[0268] Alternatively, at least one of the session management server 3, the service management server 4, and the service providing server 5 may provide the information processing apparatus 2 with data location information regarding the location where the processed image data is stored. When the data location information is received, the information processing apparatus 2 may obtain the processed image data using the data location information. Alternatively, the information processing apparatus 2 may request the image forming apparatus 1 to obtain the processed image data, by sending the data location information. Alternatively, once the data location information is obtained, the information processing apparatus 2 may cause the user I/F 204 to display the data location information to the user. The user may directly operate the image forming apparatus 1 through the operation panel 104 to cause the image forming apparatus 1 to print the processed image data. Since the operation of image forming is started only when instructed by the user, the user may instruct the image forming apparatus 1 to process a plurality of printing jobs at once such that the user is only required to go to the image forming apparatus 1 for once. This may further prevent the printed document to be left on the output tray 107 as the user is most likely to pick up the printed document after the user instructs for image forming, thus protecting the printed document from being lost or stolen.

[0269] Referring now to FIG. 18, a configuration of an image processing system is explained according to an example embodiment of the present invention. The image processing system of FIG. 18 is substantially similar to the image processing system of FIG. 1. The differences include the addition of a network D provided with an image forming apparatus 1b. The network D may be a local area network. Specifically, in this example, it is assumed that the user using the information processing apparatus 2 moves to another location away from the location where the network A is provided. In such case, the information processing apparatus 2, which is usually connected to the network A, may be connected to the network D.

[0270] Even when the information processing apparatus 2 connects to the network C through the network D, operation of image processing or image forming may be performed in a substantially similar manner as described above referring to FIGS. 11 to 17, and 25 to 27. However, in the example case illustrated in FIG. 18, the user request generated by the information processing apparatus 2 may specify the image forming apparatus 1b as the image forming apparatus 1 to print the image data.

[0271] In such case, when the user connects to the network D through the information processing apparatus 2, the registrar 305 of the image processing management apparatus 6 may obtain device information from the image forming apparatus 1b, and store the device information in the device information DB 304 in a substantially similar manner as described above referring to FIG. 6. Specifically, in this example, as illustrated in FIG. 19, the device information DB 304 shown in FIG. 7 may be updated to have device information of the image forming apparatus 1b. Once the device information stored in the device information DB 304 is updated, the printer information that is stored in the printer information manager 253 of the printing controller 205 of the information processing apparatus 2 may be updated, for example, by downloading the device information regarding the image forming apparatus 1b. Based on the updated printer information, the UI manager 255 may update the screen to notify the user that the image forming apparatus 1b is available for use.

[0272] Alternatively, the printing controller 205 of the information processing apparatus 2 may obtain device information regarding the image forming apparatus 1b by sending a request, which requests the image processing management apparatus 6 to send device information regarding an image forming apparatus connected to a local area network to which the information processing apparatus 2 is currently connected. Such request may be sent using the SOAP. In response, the image processing management apparatus 6 may search for one or more image forming apparatuses connected to the network D by referring to the address information, such as the subnet section of the IP address, of the image forming apparatus 1.

[0273] In this manner, even when the user requests to print image data using the image forming apparatus 1b, which is not previously registered in the system, the information processing apparatus 2 is capable of generating an image processing request or an image forming request without installing a printer driver specific to the image forming apparatus 1b.

[0274] Further, in this example, even when the user is logged onto the system through an information processing apparatus other than the information processing apparatus 2, the user is able to use a service provided by the information processing apparatus 2.

[0275] In another example, the user may request through the information processing apparatus 2 connected to the network D to print image data using the image forming apparatus 1a connected to the network A. In another example, the user may request through the information processing apparatus 2 connected to the network A to print image data using the image forming apparatus 1b connected to the network D. From the user's perspective, the information processing apparatus 2 may function as a facsimile capable of sending the image data to any one of the image forming apparatuses 1 provided on the network N.

[0276] Referring now to FIG. 20, a configuration of an image processing system is explained according to an example embodiment of the present invention. The image processing system of FIG. 20 is substantially similar to the image processing system of FIG. 1. The differences include the addition of a plurality of image forming apparatuses 1c and 1d, which are each connected to the network A. Specifically, in this example, the user at the information processing apparatus 2 may select one of the image forming apparatuses 1a, 1c, and 1d as an image forming apparatus 1 to perform image forming.

[0277] Even when the plurality of image forming apparatuses 1 are provided, operation of image processing or image forming may be performed in a substantially similar manner as described above referring to FIGS. 11 to 17, and 25 to 27. However, in the example case illustrated in FIG. 20, the user request generated by the information processing apparatus 2 may specify the selected one of the image forming apparatus 1a, 1c, and 1d as the image forming apparatus 1 to print the image data.

[0278] In such case, when the image forming apparatus 1c or 1d, which may be collectively referred to as the image forming apparatus 1, connects to the network A, the registrar 305 of the image processing management apparatus 6 may obtain device information from the image forming apparatus 1 in a substantially similar manner as described above referring to FIG. 6. Specifically, in this example, as illustrated in FIG. 21, the device information DB 304 shown in FIG. 7 may be updated to have device information of the image forming apparatuses 1c and 1d. Once the device information stored in the device information DB 304 is updated, the printer information that is stored in the printer information manager 253 of the printing controller 205 of the information processing apparatus 2 may be updated, for example, by downloading the device information regarding the image forming apparatuses 1c and 1d. Based on the updated printer information, the UI manager 255 may update the screen to notify the user that the image forming apparatuses 1c and 1d are available for use.

[0279] Alternatively, the printing controller 205 of the information processing apparatus 2 may obtain device information regarding the image forming apparatuses 1c and 1d by sending a request, which requests the image processing management apparatus 6 to send device information regarding an image forming apparatus connected to the network A. Such request may be sent using the SOAP. In response, the image processing management apparatus 6 may search for one or more image forming apparatuses connected to the network A by referring to the address information, such as the subnet section of the IP address, of the image forming apparatus 1.

[0280] In this manner, even when one or more image forming apparatuses are introduced to the network N, the information processing apparatus 2 is capable of generating an image processing request or an image forming request without installing a printer driver specific to the new image forming apparatus.

[0281] Referring now to FIGS. 21 to 24, image operation, image forming operation, and post processing operation, performed by the image processing system of FIG. 20, are explained according to an example embodiment of the present invention. In this example, the information processing apparatus 2 generates a user request according to a user instruction received through the user I/F 206. Specifically, in this example, it is assumed that the user request includes an image processing request that requests for specific image processing to be applied to image data to generate processed image data, an image forming request that instructs the image processing management apparatus 6 to output an image of the processed image data, and a post processing request that instructs the image processing management apparatus 6 to apply post processing to the recording sheet having the printed image thereon. In this example, the post processing request may include post processing information regarding post processing to be applied, such as stapling, punching, book-binding, folding, sorting, etc.

[0282] The structure of each apparatus provided on the image processing system of FIG. 20 is substantially similar to the structure of corresponding apparatus provided on the image processing system of FIG. 1. However, in this example, the device information DB 304 of the session management server 3 may additionally store post processing function information regarding a post processing function provided by the image forming apparatus 1 for each one of the image forming apparatuses 1a, 1c, and 1d.

[0283] Further, in this example, the printing controller 205 of the information processing apparatus 2 may be additionally provided with a post processing information manager 254 as illustrated in FIG. 22. The post processing information manager 254 manages post processing function information, which indicates various post processing functions provided by the image processing system of FIG. 20. For example, as illustrated in FIG. 23, the post processing function information may include a plurality of post processing functions including stapling, book-binding, folding, punching, etc. The post processing function information may be downloaded from the image processing management apparatus 6 in a substantially similar manner as described above referring to the example case in which the image processing function information is obtained.

[0284] In operation, when the user request is received from the information processing apparatus 2, the image processing management apparatus 6 analyzes the user request to determine how image processing, image forming, and post processing should be performed by the image processing system of FIG. 20. Specifically, in this example, the image processing management apparatus 6 determines whether the data format of the image data is interpretable by any one of the image forming apparatus 1 to generate a determination result. Further, the image processing management apparatus 6 determines whether the specific image processing can be applied by any one of the image forming apparatus 1 to generate a determination result. Further, the image processing management apparatus 6 determines whether the specific post processing can be applied by any one of the image forming apparatus 1 to generate a determination result. Based on the determination result, the image processing management apparatus 6 may generate an instruction, which specifies how a plurality of apparatuses on the network N including the image forming apparatus 1 and the information processing apparatus 2 should operate to process the user request.

[0285] Referring now to FIG. 24, operation of determining whether the specific post processing can be applied by the image forming apparatus 1a, performed by the image processing management apparatus 6, is explained according to an example embodiment of the present invention. The operation of FIG. 24 may be performed after S1403 of FIG. 14 when the determination result at S1403 indicates that the image forming apparatus 1a is capable of performing image formation ("YES" at S1403), but before the operation proceeds to S1405 of obtaining information regarding the data format and the specific image processing. For the descriptive purpose, in this example, the user request specifies the image forming apparatus 1a as the printer to process the image forming request and the post processing request.

[0286] Referring to FIG. 24, at S2401, the session management server 3 determines that the image forming apparatus 1a is capable of performing image formation based on the determination result obtained at S1403 of FIG. 14.

[0287] At S2402, the service manager 306 analyzes the user request to determine whether the post processing information indicates that any post processing is requested by the user. When the post processing information indicates that no post processing is requested ("NO" at S2402), the operation proceeds to S2406 to end the operation of FIG. 24, and further proceeds to S1405 of FIG. 14. When the post processing information indicates that any post processing is requested ("YES" at S2402), the operation proceeds to S2403.

[0288] At S2403, the service manager 306 refers to the device information DB 304 to determine whether the image forming apparatus 1a specified by the printer information of the user request is capable of applying post processing specified by the post processing information of the user request. When the image forming apparatus 1a is not capable of applying the specific post processing ("NO" at S2403), the operation proceeds to S2404. When the image forming apparatus 1a is capable of applying the specific post processing ("YES" at S2403), the operation proceeds to S2406.

[0289] At S2404, the service manager 306 refers to the device information DB 304 to search for the image forming apparatus 1 capable of applying the specific post processing to generate a search result. Based on the search result, the service manager 306 may automatically change the printer processing the request from the image forming apparatus 1a to the searched one of the image forming apparatuses 1c and 1d.

[0290] At S2405, the session manager 302 sends a notice to the information processing apparatus 2, which notifies that the printer processing the request is changed from the image forming apparatus 1a to the searched one of the image forming apparatuses 1c and 1d, and the operation further proceeds to S2406.

[0291] As described above referring to FIG. 24, the user is capable of requesting specific post processing, even when the image forming apparatus 1a is not capable of applying such specific post processing. As long as at least one device that is capable of applying the specific post processing is provided on the network N, the user may request the specific post processing. Further, in such case, the user does not have to search for the image forming apparatus that is capable of applying the specific post processing.

[0292] Further, even when there is no image forming apparatus capable of applying post processing specified by the user, the system may be changed so as to provide such post processing function, for example, by adding the image forming apparatus capable of performing the requested post processing or a post processing device capable of performing the requested post processing to the network A where the user is located. In such case, the user does not have to change the settings of any apparatus provided on the network A.

[0293] The operation of FIG. 24 may be performed in various other ways. For example, when searching for the image forming apparatus 1 capable of applying specific post processing at S2404, the image processing management apparatus 6 may only search for the image forming apparatus 1, which is assumed to be located near the user, by comparing the address information of the information processing apparatus 2 that the user is currently logged on and the address information of the image forming apparatus 1c or 1d. Alternatively, the address information of the image forming apparatus 1a may be compared with the address information of the image forming apparatus 1c or 1d.

[0294] In another example, when the search result at S2404 indicates that more than one image forming apparatus 1 can apply specific post processing, the image processing management apparatus 6 may send the search result to the information processing apparatus 2 to request the user to select one of the image forming apparatuses 1. Alternatively, the image processing management apparatus 6 may select one of the image forming apparatus 1 based on the device information, such as the address information or the status information. Alternatively, the post processing manager 254 (FIG. 22) of the printing controller 205 of the information processing apparatus 2 may only download device information regarding the image forming apparatus 1 that is assumed to be located near the information processing apparatus 2. This may prevent the user to accidentally select the image forming apparatus 1 that is not located near the location of the user, while reducing the processing load of the image processing management apparatus 6.

[0295] In another example, when the search result at S2404 indicates that there is no image forming apparatus 1 capable of applying specific post processing, the image processing management apparatus 6 may send the search result to the information processing apparatus 2, preferably together with a message that requests the user to select whether to print without applying post processing or cancel the currently performed job. Based on the user selection, the image processing management apparatus 6 may instruct the apparatus on the network N to process the user request without applying post processing or to cancel the user request.

[0296] In another example, the post processing function information may be managed together with the image processing function information, preferably by the image processing information manager 251 (FIG. 4).

[0297] In another example, the post processing function information and the image processing function information may be classified differently. For example, the image forming apparatus 1 is provided with the hardware-related function, which is mainly performed by the hardware device. The hardware-related function includes, for example, double-sided printing, in addition to the post processing described above referring to FIG. 23. Further, sorting may be performed mainly by the software device of the image forming apparatus 1 such that sorting may be classified as the image processing function.

[0298] Referring now to FIG. 28, image scanning operation, image processing operation, and image transferring operation, performed by the image processing system of FIG. 1, are explained according to an example embodiment of the present invention. In this example, the image forming apparatus 1 generates a user request according to a user instruction received through the operation panel 104. Specifically, in this example, it is assumed that the user request includes an image scanning request that request for scanning an original document into image data, an image processing request that requests for specific image processing to be applied to the image data being obtained by scanning, and an image transfer request that instructs the image processing management apparatus 6 to transfer the processed image data to the information processing apparatus 2.

[0299] When the user request is received from the image forming apparatus 1, the image processing management apparatus 6 analyzes the user request to determine how image scanning, image processing and image transferring should be performed by the image processing system of FIG. 1.

[0300] At S2801, the image forming apparatus 1 receives a user instruction for scanning an original document into image data, applying optical character recognition (OCR) processing to the image data to generate text data, and sending the text data to the information processing apparatus 2.

[0301] At S2802, the image forming apparatus 1 scans the original document, which may be provided to the ADF 101 or the scanner 102, into the image data.

[0302] At S2803, the image forming apparatus 1 generates a user request based on the user instruction. The user request includes an image processing request for applying specific image processing, which is OCR processing, to the image data, and an image transferring request for sending the text data the information processing apparatus 2. The image forming apparatus 1 further sends the user request to the session management server 3.

[0303] When the user request is received, at S2804, the session management server 3 sends an instruction to the service management server 4. The instruction may request the service management server 4 to apply OCR processing.

[0304] When the instruction and the image data are received, at S2805, the service management server 4 searches through the service providing server 5 to find a device that is capable of applying OCR processing.

[0305] At S2806, the service management server 4 sends the search result obtained at S2805 to the session management server 3. The search result may include address information or authentication information of the device of the service providing server 5 that is capable of applying OCR processing.

[0306] When the search result is received, at S2807, the session management server 3 sends an instruction including the search result to the image forming apparatus 1.

[0307] At S2808, the session management server 3 sends a session start instruction to the device of the service providing server 5 being found to request starting of a session.

[0308] At S2809 and S2810, the service providing server 5 and the image forming apparatus 1 establish a session.

[0309] When the session is established, at S2811, the image forming apparatus 1 sends the image data and the image processing information to the service providing server 5.

[0310] At S2812, the service providing server 5 applies OSR processing to the image data to generate the text data.

[0311] At S2813, the service providing server 5 sends the text data to the session management server 3.

[0312] At S2814, the session management server 3 sends the text data to the information processing apparatus 2.

[0313] At S2815, the information processing apparatus 2 stores the text data into a memory specified by the user request, and the operation ends.

[0314] As described above referring to FIG. 28, the user is capable of requesting specific image processing through the image forming apparatus 1, even when neither one of the image forming apparatus 1 and the information processing apparatus 2 is capable of applying the specific image processing. As long as at least one device that is capable of applying the specific image processing is provided on the network N, the user may request the specific image processing.

[0315] The operation of FIG. 28 may be performed in various other ways. For example, at S2801, the user instruction may be input through any apparatus other than the image forming apparatus 1, such as the information processing apparatus 2.

[0316] In another example, the text data may be stored in a memory provided at any desired location on the network N or any desired removable memory.

[0317] In another example, the image data to be processed may be stored in any desired location on the network N. As long as data location information regarding the location where the image data is stored can be obtained, the service providing server 5 may download the image data from the location, for example, without obtaining directly from the image forming apparatus 1.

[0318] In another example, the image data to be processed may be sent to the session management server 3 together with the user request.

[0319] In another example, as described above referring to FIGS. 26 and 27, for example, the specific image processing may include a plurality of image processing operations that may be applied by more than one device of the service providing server 5. In such case, the processing order may be determined by the image processing management apparatus 6.

[0320] Numerous additional modifications and variations are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the disclosure of the present invention may be practiced otherwise than as specifically described herein.
