[0035] FIG. 1 is a schematic view showing an electronic camera
system of a first embodiment.
[0036] The electronic camera system of the first embodiment has an
electronic camera 10 and a cradle 30. In a bottom portion of this
electronic camera 10, a first connecting terminal 20 is formed.
[0037] On the other hand, as shown in FIG. 1(a), in an upper face
of the cradle 30, a camera receiving part 31 for mounting the
electronic camera 10 is formed. On an inner face of the camera
receiving part 31, there are arranged a second connecting terminal
32 having a male-female relationship with the first connecting
terminal 20, and a microswitch 33. Then, as shown in FIG. 1(b),
when the electronic camera 10 is arranged on the camera receiving
part 31, the first connecting terminal 20 and the second connecting
terminal 32 engage with each other to thereby establish an
electrical connection between the electronic camera 10 and the
cradle 30. Note that the cradle 30 can detect a connection state
with the electronic camera 10 by whether the microswitch 33 is
pressed or not.
[0038] FIG. 2 is a block diagram showing a structure of the
electronic camera system of the first embodiment.
[0039] The electronic camera 10 has a photographing lens 11, an
image pickup device 12, an A/D converter 13, a buffer memory 14, an
image processing section 15, a hard disk 16, a card I/F 16a, a
liquid crystal display 17 and a manipulating member 18, a
rechargeable battery 19 which supplies power to each part of the
camera, the first connecting terminal 20, a CPU 21 and a data bus
22. Note that the buffer memory 14, the image processing section
15, the hard disk 16, the card I/F 16a, the liquid crystal display
17 and the CPU 21 are connected via the data bus 22.
[0040] The image pickup device 12 photoelectrically converts
optical flux which passes through the photographing lens 11 to
generate an analog image signal of a subject image. The A/D
converter 13 converts the analog image signal of the image pickup
device 12 into a digital image signal. The buffer memory 14
temporarily saves image data in a preceding step or a subsequent
step of image processing in the image processing section 15. The
image processing section 15 performs image processing (defective
pixel correction, gamma correction, interpolation, color
conversion, edge enhancement, and/or the like) on the digital image
signal to generate image data (moving image data or still image
data). The image processing section 15 also executes
compression/decompression processing of image data.
[0041] In the hard disk 16, the image data generated in the image
processing section 15 are recorded. This hard disk 16 has a
magnetic disk in a disk form having a surface coated with a
magnetic material, a magnetic head which reads/writes data from/to
the magnetic disk without contacting, a magnetic disk rotating
mechanism such as a spindle motor, a magnetic head driving
mechanism, and a controller which controls reading/writing of data
(a detailed structure of the hard disk is omitted from the
drawings).
[0042] In the card I/F 16a, a connector for connecting a recording
medium 23 as an auxiliary recording means is formed. The recording
medium 23 is constituted of a publicly known semiconductor memory
or the like. Then, the card I/F 16a controls writing/reading of
image data to/from the recording medium 23.
[0043] The liquid crystal display 17 displays reproduction display
of image data recorded in the hard disk 16 or the recording medium
23, a setting screen for changing various settings of the camera,
or the like. The manipulating member 18 is constituted of setting
switches used for various setting of the camera, a release button
(18a), and so forth. Also, the first connecting terminal 20 is
connected to a signal input/output line from the CPU 21 and a power
supply line to the rechargeable battery 19.
[0044] The CPU 21 controls the operation of each part of the
electronic camera according to a sequence program stored in a
not-shown ROM. For example, the CPU 21 executes
transmission/reception of various data (image data or the like)
to/from a cradle controlling section 41, which will be described
later, when being connected to the cradle 30. The CPU 21 also
executes a charging operation of the rechargeable battery when
being connected to the cradle 30.
[0045] Also, the CPU 21 holds camera side authentication
information (for example, information such as a password and a
serial number) for enabling identification of individual cameras.
Note that the camera side authentication information is transmitted
to the cradle 30 side and used for determining the possibility of
transferring image data by the cradle controlling section 41.
[0046] On the other hand, the cradle 30 has the second connecting
terminal 32, the microswitch 33, a display I/F 34 and a
communication I/F 35, a charging device 36, a recording section 37,
a management memory 38, a manipulating section 39 and a display
section 40, and a cradle controlling section 41. Note that the
second connecting terminal 32 is connected to a signal input/output
line from the cradle controlling section 41 and a power supply line
of the charging device 36.
[0047] The display I/F 34 is an interface for outputting a
reproduction display output of image data to a not-shown television
or the like. This display I/F 34 has a publicly known video output
terminal (for example, a composite video terminal, a separate video
terminal, or the like).
[0048] The communication I/F 35 controls transmission/reception of
data to/from an external apparatus (such as a personal computer)
connected to the cradle 30 in compliance with a serial
communication standard such as USB (Universal Serial Bus) or
IEEE1394. The charging device 36 is supplied with power from a
not-shown external power source and charges the rechargeable
battery 19 of the electronic camera 10 via the first connecting
terminal 20 and the second connecting terminal 32.
[0049] The recording section 37 is constituted of a hard disk or a
semiconductor memory for example. The recording capacity of the
recording section 37 is set larger than the recording capacity of
the hard disk 16 of the electronic camera 10. Accordingly, image
data taken by the electronic camera 10 can be transferred
sequentially to the recording section 37 to be saved therein.
[0050] The management memory 38 records a correspondence relation
between cradle side authentication information and processing rank
information. Here, the cradle side authentication information is
correlated with specific camera side authentication information.
The cradle side authentication information is used for identifying
on the cradle 30 side the electronic camera 10 which is allowed to
transfer image data. Note that in the management memory 38 a
plurality of cradle side authentication information can be
registered, and thereby it is possible to share one cradle 30 by a
plurality of electronic cameras 10.
[0051] Also, the processing rank information defines contents of
various processing (necessity of erasing image data on the
electronic camera 10 side and necessity of recording image data in
the recording section 37) when transferring image data of the
electronic camera system by dividing into four stages from rank A
to rank D.
[0052] Specifically, (1) in rank A, the electronic camera 10
transfers image data to the cradle 30, the image data are recorded
in the recording section 37, and the image data on the electronic
camera 10 side as a transfer source are erased. (2) In rank B, the
electronic camera 10 transfers image data to the cradle 30, and the
image data are recorded in the recording section 37 while the image
data on the electronic camera 10 side as a transfer source are
left. (3) In rank C, the electronic camera 10 transfers image data
to the cradle 30, but recording of the image data in the recording
section 37 and erasing of the image data on the electronic camera
10 side are not performed. (4) In rank D, transfer of image data
from the electronic camera 10 to the cradle 30 is prohibited. Note
that in the first embodiment, when an electronic camera whose
camera side authentication information does not correspond with the
cradle side authentication information is connected, the same
processing as the above-described rank D is performed.
[0053] The manipulating section 39 is used for instructing the
cradle controlling section 41 to perform reading of image data from
the electronic camera 10, or the like. Also, the manipulating
section 39 is used for registration setting (registration of the
electronic camera 10) of the camera side authentication information
and the cradle authentication information and setting of the
processing rank information.
[0054] The display section 40 displays information such as an
operation state of the cradle 30 and available capacity of the
recording section 37.
[0055] The cradle controlling section 41 controls each section of
the cradle 30. For example, the cradle controlling section 41
executes an operation of saving image data transferred from the
electronic camera 10 side in the recording section 37, an operation
of outputting a reproduced image of image data to the outside from
the display I/F 34, an operation of transferring image data to an
external apparatus from the communication I/F 35, and so on. Also,
the cradle controlling section 41 of the first embodiment executes
verification of the camera side authentication information and the
cradle side authentication information, and executes processing
defined in the processing rank information together with the CPU
21.
[0056] Next, with reference to a flowchart of FIG. 3, a series of
operations of the electronic camera system of the first embodiment
will be explained.
[0057] Step S101: the cradle controlling section 41 detects a
connection of the electronic camera 10 and the cradle 30 by an
input of the microswitch 33. Next, the cradle controlling section
41 communicates with the CPU 21 and obtains the camera side
authentication information from the CPU 21. Then, the cradle
controlling section 41 drives the charging device 36 to start a
charging operation of the rechargeable battery 19.
[0058] Step S102: the cradle controlling section 41 verifies the
camera side authentication information and the cradle side
authentication information to determine whether there is
corresponding cradle side authentication information or not. When
there are corresponding cradle side authentication information (YES
side), the flow goes to S103. Otherwise, when there is no
corresponding cradle side authentication information (NO side), the
cradle controlling section 41 continues the above-described
charging operation without reading image data from the electronic
camera 10. Therefore, in this case, flowing out of image data from
the electronic camera 10 to the cradle 30 against the user's
intention will not happen.
[0059] Step S103: the cradle controlling section 41 reads
processing rank information corresponding to the cradle side
authentication information in S102 and determines which of rank A
to rank D the processing rank is. When it is the rank A, the flow
goes to S104. When it is the rank B, the flow goes to Si05. When it
is the rank C, the flow goes to S106. Then, when it is the rank D,
the cradle controlling section 41 continues the above-described
charging operation without reading image data from the electronic
camera 10. In this case, flowing out of image data from the
electronic camera 10 to the cradle 30 against the user's intention
will not happen.
[0060] Step S104: the cradle controlling section 41 requests the
CPU 21 to transfer image data. The CPU 21 transfers image data to
the cradle 30 from the hard disk 16 or the recording medium 23, and
erases the image data in the transfer source. Then, the cradle
controlling section 41 records the transferred image data in the
recording section 37. Specifically, in the case of S104, the image
data are stored in the cradle 30, and the transferred image data
are deleted automatically from the electronic camera 10 and thereby
the number of photographable frames are increased accordingly.
[0061] On the other hand, the user can view the image data recorded
in the recording section 37 of the cradle 30 on a television or the
like or can even transfer the image data from the cradle 30 to an
external apparatus. Note that in S104, when available capacity in
the recording section 37 runs out, the CPU 21 stops transfer and
deletion of image data, and the cradle controlling section 41
performs alarm display meaning "defragmentation cannot be executed
due to insufficient available capacity in the recording section 37"
by a text, an icon or the like on the display section 40.
[0062] Step S105: the cradle controlling section 41 requests the
CPU 21 to transfer image data. The CPU 21 transfers image data to
the cradle 30 from the hard disk 16 or the recording medium 23.
Then, the cradle controlling section 41 records the transferred
image data in the recording section 37. Specifically, in the case
of S105, while the image data are stored in the cradle 30, the
image data in the transfer source are left as they are in the
electronic camera 10. This processing in S105 is suitable when it
is desired to save and carry favorite image data on the electronic
camera 10 side, or when image data are backed up in a plurality of
cradles 30.
[0063] Step S106: the cradle controlling section 41 requests the
CPU 21 to transfer image data. The CPU 21 transfers image data to
the cradle 30 from the hard disk 16 or the recording medium 23.
Then, the cradle controlling section 41 outputs a reproduced image
based on the transferred image data from the display I/F 34 to a
television or the like. At this time, the cradle controlling
section 41 does not perform recording of the imaged data in the
recording section 37 and transferring of image data to an external
apparatus. The processing in S106 is suitable when for example the
electronic camera 10 is connected to another person's cradle 30 to
reproduce a photographed image, or the like. Thus, an explanation
of the operation of the first embodiment is completed.
[0064] Effects of the electronic camera system of the first
embodiment will be explained below.
[0065] (1) In the first embodiment, image data are transferred from
the electronic camera 10 to the cradle 30 only when the camera side
authentication information and the cradle side authentication
information have a correspondence relation (S102 to S106).
Specifically, image data are transferred to the cradle 30 only when
the user permits transfer of image data in advance by registration
setting of authentication information, and thus flowing out of
image data against the user's intention can be prevented. Also, the
electronic camera 10 can be charged by connecting the electronic
camera 10 and the cradle 30.
[0066] (2) In the first embodiment, since the transfer sequence of
image data is executed automatically with an input of the
microswitch 33 being a trigger (S101), complication in manipulation
when transferring image data is eliminated. Also, since setting for
when transferring image data can be customized in detail by
registering the processing rank information, an electronic camera
system with high convenience for users can be realized.
Explanation of Second Embodiment
[0067] FIG. 4 is a block diagram showing a structure of an
electronic camera system of a second embodiment. Note that in the
following explanations of embodiments, components which are common
to the first embodiment are assigned the same reference numerals,
and explanations thereof are omitted.
[0068] The second embodiment is a modification example of the first
embodiment, and has a structure different from the first embodiment
in that a management memory 24 recording a correspondence relation
between the camera side authentication information and the
processing rank information is provided on the electronic camera 10
side. Also, the CPU 21 of the second embodiment has a function to
determine a possibility of transferring image data and various
processing when transferring image data. Then, only the cradle side
authentication information is recorded in the management memory 38
on the cradle 30 side.
[0069] In this second embodiment, the cradle controlling section 41
transmits the cradle side authentication information when the
electronic camera 10 and the cradle 30 are connected, and the CPU
21 determines a possibility of transferring image data and various
processing during transfer of image data. Also with the structure
of the second embodiment, almost the same effects as in the first
embodiment can be obtained.
Explanation of Third Embodiment
[0070] FIG. 5 is a flowchart explaining a series of operations of
an electronic camera system of a third embodiment. Here, S205 to
S207 of the third embodiment correspond respectively to S104 to
S106 of the first embodiment, and hence duplicating explanations
are omitted. Also, a block diagram of the electronic camera system
of the third embodiment is common to the first embodiment and hence
omitted from the drawings.
[0071] In this third embodiment, authentication information
(password) set by the user is stored as the cradle side
authentication information in the management memory 38, and the
cradle controlling section 41 determines a possibility of
transferring image data based on authentication information
inputted by the user. Also, in the third embodiment, a processing
rank corresponding to the processing rank information (rank A to
rank C) of the first embodiment is inputted by the user.
[0072] Step S201: the cradle controlling section 41 detects a
connection of the electronic camera 10 and the cradle 30 by an
input of the microswitch 33. Next, the cradle controlling section
41 displays on the display section 40 a display to prompt inputting
of authentication information and a processing rank (selection of
the rank A to the rank C of the processing rank information of the
first embodiment). Then, the cradle controlling section 41 drives
the charging device 36 to start a charging operation of the
rechargeable battery 19.
[0073] Step S202: the cradle controlling section 41 determines
whether or not there are inputs of authentication information and a
processing rank by the user from a manipulating section of the
electronic camera 10 or the manipulating section of the cradle 30.
When there are inputs (YES side), the flow goes to S203. When there
are no input (NO side), the cradle controlling section 41 waits for
an input by the user. Note that when there is no input for a
predetermined time, the cradle controlling section 41 finishes the
processing as it is, and continues only the aforementioned charging
operation.
[0074] Step S203: The cradle controlling section 41 verifies the
inputted authentication information and the authentication
information in the management memory 38, and determines whether the
inputted authentication information is valid or not. When the
authentication information is valid (YES side), the flow goes to
S204. On the other hand, when the authentication information is not
valid (NO side), the flow returns to S202.
[0075] Step S204: the cradle controlling section 41 determines
which of the rank A to the rank C the processing rank inputted with
the authentication information is. When it is the rank A, the flow
goes to S205. When it is the rank B, the flow goes to S206. When it
is the rank C, the flow goes to S207.
[0076] Also in the above-described third embodiment, image data are
transferred to the cradle 30 only when the user permits transfer of
image data by registration setting of authentication information,
and thus flowing out of image data against the user's intention can
be prevented.
Explanation of Fourth Embodiment
[0077] Next, an electronic camera system of a fourth embodiment
will be explained. A basic structure of the electronic camera
system of the fourth embodiment is common to the electronic camera
10 and the cradle 30 shown in FIG. 4, and functions of part of
components are different from the above embodiments. Accordingly,
in the explanation of the fourth embodiment, a block diagram is
omitted from the drawings, and components corresponding to the
above embodiments are assigned the same reference numerals and
duplicating explanations are omitted.
[0078] In the fourth embodiment, in the management memory 24 of the
electronic camera 10, camera side authentication information and
camera side connection history data are recorded. The camera side
authentication information is constituted of different data for
each of electronic cameras 10, and used by the cradle 30 as a
connecting destination for identifying each of the electronic
cameras 10. As an example, as the camera side authentication
information, a serial number or a manufacturing code of the
electronic camera 10 can be used. Of course, as the camera side
authentication information, an arbitrary symbol sequence assigned
to each of the electronic cameras 10 besides the serial number and
so on may be used.
[0079] FIG. 6(a) is a view schematically showing the camera side
connection history data. In the camera side connection history
data, every time the electronic camera 10 is connected to the
cradle 30, a connection history is recorded in a time-series manner
by the CPU 21. In the camera side connection history data, as a
connection history of one time, a connection date and time, cradle
side authentication information indicating the cradle 30 as a
connecting destination, and an operation mode when being connected
are recorded in a correlated state.
[0080] Here, the operation mode defines a manipulation which can be
executed by the user in a state that the electronic camera 10 and
the cradle 30 are connected. Note that an explanation of the cradle
side authentication information will be described later. In an
example of FIG. 6(a), data of one line correspond to a connection
history of one time, and the connection histories become newer as
they go downward.
[0081] The CPU 21 of the electronic camera 10 controls
transmission/reception of data to/from the cradle 30 as a
connecting destination and also manages the camera side connection
history data. Particularly, the CPU 21 transmits the camera side
authentication information to the cradle 30 when being connected to
the cradle 30. Also, the CPU 21 searches for the camera side
connection history data based on the cradle side authentication
information, which will be described later, received from the
cradle 30 when being connected to the cradle 30 and returns a
search result to the cradle 30.
[0082] In the management memory 38 of the cradle 30, the cradle
side authentication information and cradle side connection history
data are recorded. The cradle side authentication information is
constituted of different data for each of cradles 30, and used by
the electronic camera 10 as a connecting destination for
identifying each of the cradles 30. As an example, as the cradle
side authentication information, a serial number or a manufacturing
code of the cradle 30 can be used. Of course, as the cradle side
authentication information, an arbitrary symbol sequence assigned
to each of the cradles 30 besides the serial number and so on may
be used.
[0083] FIG. 6(b) is a view schematically showing the cradle side
connection history data. In the cradle side connection history
data, every time the cradle 30 is connected to the electronic
camera 10, a connection history is recorded in a time-series manner
by the cradle side controlling section 41. In the cradle side
connection history data, as a connection history of one time, a
connection date and time, the camera side authentication
information indicating the electronic camera 10 as a connecting
destination, and an operation mode when being connected are
recorded in a correlated state. In an example of FIG. 6(b), data of
one line correspond to a connection history of one time, and the
connection histories become newer as they go downward.
[0084] The cradle controlling section 41 of the cradle 30 controls
transmission/reception of data to/from the cradle 30 as a
connecting destination and also manages the cradle side connection
history data. Particularly, the cradle controlling section 41
transmits the cradle side authentication information to the
electronic camera 10 when being connected to the electronic camera
10. Also, the cradle controlling section 41 searches for the cradle
side connection history data based on the camera side
authentication information received from the electronic camera 10
when being connected to the electronic camera 10.
[0085] Also, the cradle controlling section 41 determines the
above-described operation mode when being connected to the
electronic camera 10, and executes the overall control of the
entire system in a state that the electronic camera 10 and the
cradle 30 are connected. Here, the cradle controlling section 41
can select the operation mode from either of the first operation
mode and the second operation mode when deciding the operation
mode.
[0086] In the first operation mode, when the electronic camera 10
and the cradle 30 are connected, the user can perform various
manipulations with almost no constraint. This first operation mode
is selected, for example, in a situation that the user permits
transfer of data or the like between the electronic camera 10 and
the cradle 30, such as when the owners of the electronic camera 10
and the cradle 30 match.
[0087] On the other hand, in the second operation mode, the user is
restricted in executable manipulation as compared to the first
operation mode. This second operation mode is selected, for
example, in a situation that the owners of the electronic camera 10
and the cradle 30 are different, and the user thinks that it is
favorable to prevent flowing out of data from occurring. Note that
specific contents of operations of the first operation mode and the
second operation mode will be described later.
[0088] Operations of the CPU 21 and the cradle controlling section
41 in selection of the operation mode in the fourth embodiment will
be explained below with reference to the flowchart of FIG. 7.
[0089] Step 301: upon detection of a connection of the electronic
camera 10 and the cradle 30 by an input of the microswitch 33, the
cradle controlling section 41 of the cradle 30 transmits the cradle
side authentication information to the electronic camera 10.
[0090] Step 302: upon reception of the cradle side authentication
information (S301), the CPU 21 of the electronic camera 10
transmits the camera side authentication information to the cradle
30.
[0091] Step 303: the CPU 21 of the electronic camera 10 searches
for the camera side connection history data based on the cradle
side authentication information (S301), and sequentially executes
the following processing of (a1) to (a3).
[0092] (a1) Firstly, the CPU 21 determines whether there is a prior
connection history or not (in other words, whether the electronic
camera 10 has never been connected to the cradle 30). When there is
a prior connection history, the CPU 21 performs the next processing
of (a2). On the other hand, when there is no prior connection
history, the CPU 21 notifies the cradle 30 that a connection of
this time is a first connection. Note that in this case, the CPU 21
does not need to perform the processing of (a2) and thereafter in
S303.
[0093] (a2) Secondly, the CPU 21 determines whether cradle side
authentication information corresponding to the oldest connection
history and the cradle side authentication information (S301) of
this time match or not (in other words, whether the electronic
camera 10 has been connected to a plurality of cradles 30 or not).
When the both match, the CPU 21 notifies the cradle 30 that the
cradle 30 is determined to match with a connecting destination of a
first connection. Note that in this case, the CPU 21 does not need
to perform the processing of (a3) and thereafter in Step S303. On
the other hand, when the both do not match, the CPU 21 performs the
next processing of (a3).
[0094] (a3) Thirdly, the CPU 21 extracts connection histories
corresponding to the cradle side authentication information (S301)
of this time. Then, the CPU 21 notifies the cradle 30 of an
operation mode recorded in the latest connection history among
extracted connection histories. Note that when there is no
connection history corresponding to the cradle side authentication
information (S301) of this time in the electronic camera 10, the
CPU 21 instructs the cradle 30 to select the second operation
mode.
[0095] Step 304: on the other hand, the cradle controlling section
41 of the cradle 30 searches for the cradle side connection history
data based on the camera side authentication information (S302) and
sequentially executes the following processing of (b1) to (b3).
Note that the cradle controlling section 41 can execute the
operation of S304 almost in parallel to the operation of S303 on
the electronic camera 10 side.
[0096] (b1) Firstly, the cradle controlling section 41 determines
whether there is a prior connection history or not (in other words,
whether the cradle 30 has never been connected to the electronic
camera 10). When there is a prior connection history, the cradle
controlling section 41 performs the next processing of (b2). On the
other hand, when there is no prior connection history, the cradle
controlling section 41 determines that that a connection of this
time is a first connection. Note that in this case, the cradle
controlling section 41 does not need to perform the processing of
(b2) and thereafter in S304.
[0097] (b2) Secondly, the cradle controlling section 41 determines
whether camera side authentication information corresponding to the
oldest connection history and the camera side authentication
information (S302) of this time match or not (in other words,
whether the cradle 30 has been connected to a plurality of
electronic cameras 10 or not). When the both match, the cradle
controlling section 41 determines that the electronic camera 10
match with a connecting destination of a first connection. Note
that in this case, the cradle controlling section 41 does not need
to perform the processing of (b3) and thereafter in Step S304. On
the other hand, when the both do not match, the cradle controlling
section 41 performs the next processing of (b3).
[0098] (b3) Thirdly, the cradle controlling section 41 extracts
connection histories corresponding to the camera side
authentication information (S302) of this time. Then, the cradle
controlling section 41 obtains data of an operation mode recorded
in the latest connection history among extracted connection
histories. Note that when there is no connection history
corresponding to the camera side authentication information (S302)
of this time in the cradle 30, the cradle controlling section 41
selects the second operation mode.
[0099] Step 305: the cradle controlling section 41 determines
whether the electronic camera 10 and the cradle 30 are mutually in
a first connection or not based on the processing results in S303
and S304.
[0100] When being mutually in a first connection (YES side), it
corresponds to the case where an owner connects the electronic
camera 10 and the cradle 30 for the first time which are both brand
new for example, and it is conceivable that there is a low
possibility that owners of the electronic camera 10 and the cradle
30 are different. Accordingly, the cradle controlling section 41
goes to S310.
[0101] On the other hand, when at least one of the electronic
camera 10 and the cradle 30 is not in a first connection (NO side),
there is a high possibility that owners of the electronic camera 10
and the cradle 30 are different. Accordingly, the cradle
controlling section 41 goes to S306 to further perform the
following determination.
[0102] Step 306: the cradle controlling section 41 determines
whether or not the electronic camera 10 and the cradle 30 mutually
match with a connecting destination of a first connection based on
the processing results in S303 and S304.
[0103] When mutually matching with a connecting destination of a
first connection (YES side), it is conceivable that there is a low
possibility that owners of the electronic camera 10 and the cradle
30 are different. Therefore, the cradle controlling section 41 goes
to S310.
[0104] On the other hand, when at least one of the electronic
camera 10 and the cradle 30 is not a connecting destination of a
first connection (NO side), there is a high possibility that owners
of the electronic camera 10 and the cradle 30 are different.
Accordingly, the cradle controlling section 41 goes to S307 and
further performs the following determination.
[0105] Step 307: the cradle controlling section 41 determines
whether the operation mode of the latest connection history is the
first operation mode or not based on the processing results in S303
and S304. When the above condition is satisfied (YES side), it is
conceivable that the user allows an operation in the first
operation mode in this combination of the electronic camera 10 and
the cradle 30. Accordingly, the cradle controlling section 41 goes
to S310. On the other hand, when the above condition is not
satisfied (NO side), the cradle controlling section 41 goes to
S308.
[0106] Step 308: the cradle controlling section 41 displays a
confirmation screen of an operation mode on the display section 40
or the like. This confirmation screen includes a message to confirm
with the user whether to limit the function or not when being
connected (whether to connect in the second operation mode or not)
and selection items (items such as Yes/No) which can be inputted
via a GUI format. Then, the cradle controlling section 41 accepts a
specification input regarding the aforementioned selection items
via the manipulating section 39 from the user. Note that the
confirmation screen is omitted from the drawings.
[0107] Step 309: the cradle controlling section 41 determines
whether or not there is a specifying input to maintain the
operation mode in the second operation mode in S308. In the case
(YES side) of a specifying input of an item to maintain the
operation mode (item Yes in the confirmation screen), the flow goes
to S311. On the other hand, in the case of a specifying input of an
item to change the operation mode (item No in the confirmation
screen), the flow goes to S310.
[0108] Step 310: in this case, the cradle controlling section 41
selects the first operation mode. Thereafter, the cradle
controlling section 41 goes to S312.
[0109] Step 311: in this case, the cradle controlling section 41
selects the second operation mode.
[0110] Step 312: the cradle controlling section 41 adds data of a
connection history of this time to the cradle side connection
history data in the management memory 38. Also, the cradle
controlling section 41 transmits data of the connection history of
this time to the electronic camera 10.
[0111] Step 313: The CPU 21 of the electronic camera 10 adds data
of the connection history of this time to the camera side
connection history data in the management memory 24 based on the
data transmitted in S312. Thus, the explanation of the flowchart of
FIG. 7 is completed.
[0112] Next, differences in control of the cradle controlling
section 41 in the first operation mode and the second operation
mode are explained specifically.
[0113] (A) the cradle controlling section 41 in the first operation
mode can read image data in the electronic camera 10 and reproduce
and display the image data. Specifically, the cradle controlling
section 41 can read temporarily the image data into a buffer memory
(not shown) of the cradle 30 from the electronic camera 10, and
output a reproduced image to the display section 40 or the display
I/F 34. The cradle controlling section 41 in the first operation
mode can also reproduce and display image data to which protection
is specified, which means that reproduction and erasing in other
apparatuses are prohibited.
[0114] On the other hand, the cradle controlling section 41 in the
second operation mode can read, reproduce and display image data in
the electronic camera 10, similarly to the first operation mode.
However, the cradle controlling section 41 in the second operation
mode always execute an operation of erasing image data from the
buffer memory of the cradle 30 after reproduction is finished.
Accordingly, a problem that reproduction and display of image data
are performed only by the cradle 30 without limit by the image data
remaining in the buffer memory of the cradle 30 can be
prevented.
[0115] Also, the cradle controlling section 41 in the second
operation mode prohibits reproduction and display of image data to
which the above-described protection is specified. Therefore, in
the second operation mode, image data to which the protection is
specified will not be reproduced against the user's intention. Of
course, also in the second operation mode, the cradle controlling
section 41 may individually reproduce and display image data to
which the protection is specified based on a manipulation by the
user from the manipulating section 39. Note that when image data to
which the protection is specified is to be reproduced and displayed
in the second operation mode, it is preferable that the cradle
controlling section 41 requests the user for authentication such as
inputting of a password.
[0116] (B) the cradle controlling section 41 in the first operation
mode can transfer image data in the electronic camera 10 to the
recording section 37 for recording. Also, the cradle controlling
section 41 in the first operation mode can instruct the CPU 21 to
erase image data in the transfer source on the electronic camera 10
side. Of course, the cradle controlling section 41 can also leave
the image data in the transfer source as they are in the electronic
camera 10 and copy the image data.
[0117] Further, the cradle controlling section 41 in the first
operation mode can limit image data to be transferred to the cradle
30 for recording. For example, when pay image data which are
purchased by downloading are recorded in the electronic camera 10,
the cradle controlling section 41 refers to information in the
header of the pay image data to prohibit copying to the cradle 30.
In this case, the cradle controlling section 41 can transfer only
image data photographed by the electronic camera 10 to the cradle
30 for recording. Note that when a sample image having a low
resolution that can be distributed freely is attached to the
aforementioned pay image data, the cradle controlling section 41
may permit transfer and recording of the aforementioned sample
image.
[0118] On the other hand, the cradle controlling section 41 in the
second operation mode prohibits transfer of image data in the
electronic camera 10 to the recording section 37 for recording.
Therefore, in the second operation mode, the image data recorded in
the electronic camera 10 will not flow out to the cradle 30 against
the user's intention. Of course, in the second operation mode, the
cradle controlling section 41 may transfer to the recording section
37 image data which are individually specified by the user by a
manipulation from the manipulating section 39 or the like. As an
example, by pressing the release button 38a of the electronic
camera 10 by the user when image data is reproduced and displayed,
the cradle controlling section 41 transfers to the recording
section 37 the image data which are being reproduced and displayed.
Note that when transfer of image data is performed in the second
operation mode, it is preferable that the cradle controlling
section 41 requests the user for authentication such as inputting
of a password.
[0119] (C) The cradle controlling section 41 in the first operation
mode can transfer image data from the recording section 37 of the
cradle 30 to the electronic camera 10. The cradle controlling
section 41 can also erase image data in a transfer source existing
in the recording section 37. Of course, the cradle controlling
section 41 can also leave the image data in the transfer source in
the recording section 37 as they are and copy the image data.
Further, the cradle controlling section 41 in the first operation
mode can also limit image data to be transferred to the electronic
camera 10, similarly to the above-described (B).
[0120] On the other hand, the cradle controlling section 41 in the
second operation mode prohibits transfer of image data from the
recording section 37 of the cradle 30 to the electronic camera 10.
Therefore, in the second operation mode, image data recorded in the
cradle 30 will not flow out to the electronic camera 10 against the
user's intention. Of course, also in the second operation mode, the
cradle controlling section 41 may transfer to the electronic camera
10 image data which are specified individually by the user by a
manipulation from the manipulating section 39 or the like. Note
that when performing transfer of image data to the electronic
camera 10 in the second operation mode, it is preferable that the
cradle controlling section 41 requests the user for authentication
such as inputting of a password.
[0121] Here, when image data transferred from a plurality of
electronic cameras 10 are recorded in the recording section 37, the
cradle controlling section 41 may prohibit re-transfer of image
data transferred from different electronic cameras 10.
Specifically, in this case, only returning of image data which are
transferred before from the electronic camera 10 as a connecting
destination is allowed. For example, based on information (serial
number) of the electronic camera 10 recorded in a header of
respective image data, the cradle controlling section 41 transfer
the image data to the electronic camera 10 when the electronic
camera 10 as a transfer source match with the electronic camera 10
as a transfer destination. Thus, prevention of flowing out of image
data against the user's intention becomes easy.
[0122] (D) The cradle controlling section 41 in the first operation
mode reads image data from the electronic camera 10 and can output
image data to an external apparatus via the communication I/F 35.
Thus, the user can perform, for example, (1) saving of image data
in an external apparatus, (2) printing of a screen by an external
apparatus having a printing function (3) uploading of image data to
a homepage or the like on the Internet, (4) mail distribution of
image data, and so on.
[0123] On the other hand, the cradle controlling section 41 in the
second operation mode prohibits outputting of image data to an
external apparatus via the communication I/F 35. Therefore, in the
second operation mode, image data will not flow out to the external
apparatus against the user's intention. Of course, also in the
second operation mode, the cradle controlling section 41 may output
image data which are specified individually by the user by a
manipulation from the manipulating section 39 or the like to the
external apparatus. Note that when performing outputting of image
data to the external apparatus in the second operation mode, it is
preferable that the cradle controlling section 41 requests the user
for authentication such as inputting of a password.
[0124] (E) The cradle controlling section 41 in the first operation
mode executes an editing manipulation of image data in the
recording section of the cradle 30 by an input by the user from the
manipulating member 18 of the electronic camera 10. Also, the
cradle controlling section 41 in the first operation mode executes
an editing manipulation of image data recorded in the recording
medium 23 of the electronic camera 10 or the like, by an input from
the manipulating section 39 of the cradle 30.
[0125] Here, the editing manipulation of image data includes (1)
erasing of image data, (2) changing of status of image data (for
example, execution/release of protection specification), (3) image
processing on image data, (4) generation of print setting data
complying with the DPOF (Digital Print Order Format) standard, (5)
generation of scenario data for reproduction, and so on. Note that
in the scenario data for reproduction, there are recorded data
indicating a display order in the case where images of a plurality
of image data are reproduced sequentially, display timing, video
effects, BGM and sound effects during reproduction, and so on.
[0126] On the other hand, the cradle controlling section 41 in the
second operation mode prohibits an editing manipulation of image
data recorded in the cradle 30 from the manipulating member 18 of
the electronic camera 10. Also, the cradle controlling section 41
in the second operation mode prohibits an editing manipulation of
image data recorded in the electronic camera 10 from the
manipulating section 39 of the cradle 30. Thus, when the electronic
camera 10 and the cradle 30 are connected, tampering of data from
an apparatus as a connecting destination can be prevented.
[0127] (F) The cradle controlling section 41 in the first operation
mode transfers between the electronic camera 10 and the cradle 30
the aforementioned print setting data and scenario data for
reproduction similarly to image data.
[0128] On the other hand, the cradle controlling section 41 in the
second operation mode prohibits transfer and copying of the
aforementioned print setting data and scenario data for
reproduction between the electronic camera 10 and the cradle 30.
This is because there is a fear that printing or reproduction of an
image is performed against the user's intention by executing these
data. Of course, also in the second operation mode, the cradle
controlling section 41 may execute transfer and copying of the
aforementioned print setting data and scenario data for
reproduction according to a manipulation from the manipulating
section 39. Note that in this case, it is preferable that the
cradle controlling section 41 requests the user for authentication
such as inputting of a password.
[0129] (G) The cradle controlling section 41 in the first operation
mode executes charging of the electronic camera 10 when the
electronic camera 10 and the cradle 30 are connected. On the other
hand, the cradle controlling section 41 in the second operation
mode can switch on/off of a charging function of the electronic
camera 10 according to setting by the user.
[0130] (H) The cradle controlling section 41 in the first operation
mode executes, if necessary, defragmentation of the hard disk 16 of
the electronic camera 10 when the electronic camera 10 and the
cradle 30 are connected. Also, the cradle controlling section 41 in
the first operation mode executes, if necessary, updating of a
firmware program of the electronic camera 10 when the electronic
camera 10 and the cradle 30 are connected. On the other hand, the
cradle controlling section 41 in the second operation mode do not
execute defragmenation of the hard disk 16 or updating of the
firmware program.
[0131] Effects of the fourth embodiment will be explained
below.
[0132] In the electronic camera system of the fourth embodiment,
the cradle controlling section 41 selects the operation mode when
being connected based on authentication results of the electronic
camera 10 and the cradle 30. Then, when the cradle controlling
section 41 operates in the first operation mode, the user can
perform various manipulations with almost no constraint. On the
other hand, when the cradle controlling section 41 operates in the
second operation mode, the user is restricted significantly in
terms of reproduction of an image, transfer of image data, and so
on with the cradle 30. Accordingly, in the electronic camera system
of the fourth embodiment, flowing out of image data against the
user's intention can be prevented easily.
[0133] Also, in the electronic camera system of the fourth
embodiment, the operation mode when being connected is selected
based on a connection history by the camera side connection history
data and the cradle side connection history data. Therefore, since
the cradle controlling section 41 selects the optimum operation
mode according to a situation, the user does not need to perform a
troublesome setting manipulation.
Explanation of Fifth Embodiment
[0134] FIG. 8 is a block diagram showing a structure of an
electronic camera system of a fifth embodiment. The electronic
camera system of the fifth embodiment is a modification example of
the fourth embodiment, in which the electronic camera 10 and the
cradle 30 can transmit/receive image data via radio communication.
Note that also in FIG. 8, components corresponding to the above
embodiments are assigned the same reference numerals and
duplicating explanations are omitted.
[0135] The electronic camera 10 and the cradle 30 of the fifth
embodiment further have radio communication modules 25, 42,
respectively. The radio communication modules 25, 42 control
communication with another radio communication module in compliance
with the specification defined in IEEE802.11, which is a standard
for wireless LAN. For example, when transmitting image data to
another apparatus, the radio communication modules 25, 42 convert
the image data into data which can be radio-communicated, and data
after the conversion are transmitted to another apparatus via an
antenna (not shown).
[0136] In this fifth embodiment, even when the electronic camera 10
and the cradle 30 are not connected via the connecting terminals,
it becomes possible to manage transfer of image data and management
of reproduction, similarly to the fourth embodiment.
Supplementary Items of the Embodiments
[0137] (1) The cradle of the present invention is not limited to
the case of being constituted of a single apparatus as in the
above-described embodiments. For example, a structure (omitted from
the drawings) is possible such that the cradle is connected to a
personal computer and the personal computer realizes the functions
of the cradle controlling section 41, the recording section, and so
on in the above-described embodiments.
[0138] (2) In the above-described embodiments, an example of
starting the transfer sequence of image data with detection of a
connection of the electronic camera and the cradle by the
microswitch being a trigger is explained. However, in the present
invention, the transfer sequence may be started with a transfer
instructing manipulation by the user being a trigger (for example,
pressing a transfer button on the cradle). Also, a means (for
example, a microswitch, detection of a connection by conduction of
the first connecting terminal, or the like) to detect a connection
with the cradle may be provided on the electronic camera side.
[0139] (3) In the above-described embodiments, an example of
performing transfer of image data and a charging operation in
parallel is shown, but the present invention embraces both a
structure to charge the rechargeable battery after transfer
processing of image data finishes and a structure to executes
transfer processing of image data after charging finishes.
[0140] (4) Also in the third embodiment, the authentication
information and the processing rank information may be correlated
and recorded in the management memory, and inputting of a
processing rank by the user may be omitted.
[0141] (5) In the third embodiment, a publicly known biometrics
authentication means (for example, a finger print recognition
apparatus, an iris recognition apparatus, or the like) may be
provided in the electronic camera or the cradle, and the user may
input authentication information with the biometrics authentication
means (note that the biometrics authentication means is omitted
from the drawings).
[0142] (6) In the above-described fourth embodiment, an example in
which the cradle controlling section 41 performs the overall
control of the electronic camera system is explained. However, in
the present invention, a structure is possible such that the
electronic camera executes the overall control of the electronic
camera system, and the CPU 21 executes selection of the first
operation mode and the second operation mode and control in the
respective operation modes.
[0143] (7) In the above-described fourth embodiment, there is
explained a structure in which the electronic camera and the cradle
records data of a connection history respectively, and the
connection history and the authentication information are verified
in both the apparatuses. However, in the present invention, a
structure is possible such that only either the electronic camera
or the cradle records the data of a connection history and thereby
data of a connection history of one are verified with
authentication information in the other apparatus. Also, in the
fourth embodiment, a correspondence relation between the
authentication information and the operation mode may be recorded
in the management memory of one apparatus, and the one apparatus
may determine the operation mode based on the authentication
information in the other apparatus. In this case, recording of the
data of a connection history is no longer necessary.
[0144] (8) In selection of the operation mode in the fourth
embodiment, when the first operation mode is selected in the
confirmation screen (S308), the cradle controlling section 41 may
request for authentication such as inputting of a password.
[0145] (9) In the fifth embodiment, an example of constructing the
electronic camera system with the electronic camera and the cradle
which have a radio communication function is explained. However, in
the present invention, without being limited to the cradle, the
electronic camera system corresponding to the fifth embodiment can
be constituted of a combination of an electronic camera and an
image storage apparatus, each of which having a radio communication
function.
[0146] (10) In the fifth embodiment, an example of performing data
communication of the electronic camera via a wireless LAN is
explained, but the radio communication means between the electronic
camera and the image storage apparatus is not limited to the above
description. For example, as the radio communication means, IRDA,
DLNA, Bluetooth (registered trademark), a telephone line or
satellite communication may be used.
[0147] (11) Note that in the above-described embodiments, an
example of data transmission/reception of image data is mainly
explained, but for example audio data or the like may be included
in the subject of the data communication.
