1. Field
[0002] The present invention relates to a transferring system, and
particularly, to a transferring system of huge and high quality
images on network and a method thereof.
2. Background
[0003] Nowadays, it takes much time to display high quality image
data in a client computer through Internet service because of a
limitation of network bandwidth or processing time in a main memory
unit. That requires expansion of the network bandwidth and
increased capacity of a main memory unit, resulting in increasing
cost of an overall system.
[0004] In the related art, newspaper and magazine service through
Internet is performed mainly with text or PDF format. The text
service provides information with only letters, thereby having a
limitation in added image information and various contents
construction. Also, in PDF form, a file is downloaded according to
a corresponding page on Internet and data are read by using a
special program.
[0005] In the related art, even if the method is used by some
newspaper and magazine service, a user has to download his wanted
page each time and can see the part after completing the download,
thereby not providing overall contents real time. Also, a
constitution and a user interface of the downloaded page are not
intuitive, and in case of PDF, screen renewal time is influenced by
a function of the user's computer system, resulting in that the
method is not proper to real time service of high quality image
data.
SUMMARY OF THE INVENTION
[0006] Therefore, an object of the present invention is to provide
a transferring system which fast transmits image information
without extending network bandwidth and increasing capacity of a
main memory device and displays the image information real time and
a method thereof.
[0007] Especially, an object of the present invention is to provide
a method in which a form of newspaper and magazine offered off-line
is originally converted into high quality image data to provide
real time on-line, and various multimedia contents and additional
information are connected to be utilized as a synthetic information
offering media.
[0008] To achieve these and other advantages and in accordance with
the purpose of the present invention, as embodied and broadly
described herein, there is provided a transferring system for huge
and high quality image on network comprising an image converting
system for converting digital information into a high quality image
format, the digital information such as image information converted
into a file possible to work in a computer or image information
read from a scan device; an image database for storing high quality
image information made in the image converting system; and a server
system for transmitting image information stored in the image
database on network by a request of a client system.
[0009] Also, in the present invention, there is provided a method

DETAILED DESCRIPTION
[0025] Reference will now be made in detail to the preferred
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings.
[0026] A transferring system for huge and high quality images on
network comprises a system for making original data be digital by a
regular rule and converting the data into high quality image
format; a database for storing the digital image data and managing;
and a server system for transferring the data real time on
network.
[0027] Referring to FIG. 1, a server system 10 possible to include
a transferring system 12 extracts necessary information by
connecting an image converting system 20 for generating high
quality image data and a database 30 and then transmits the
information on network. The database 30 can additionally include an
image database 32 having image information and an additional
information database 34 having additional information.
[0028] In a method for transferring image data according to the
present invention, as shown in FIG. 2, a server/client model is
applied and then data are transmitted real time between the server
system 10 and the client system 40.
[0029] With respect to a client system, one or more systems
simultaneously communicate with the server system on network, and
each client system includes a central processing unit and at least
one memory unit and a display unit.
[0030] FIG. 3a is a schematic view showing a related art image
service. Image data stored in database 50b of server 50a are
transmitted to the client system through network 51 by a request of
a client system, and displayed on a screen window 55 through a
video buffer 54 via main memory 53a, 53b, . . . 53'. At this time,
since capacity of image data is much greater than another
information, the main memory unit of the client system has to be
large, and long transmittance time causes delay until the data are
displayed on a screen window. Also, as capacity of image data is
restricted by physical capacity of the main memory 53a, 53b, . . .
53', there is a limit to provide huge and high quality image data
real time.
[0031] Meanwhile, in the transferring method, as shown in FIG. 3b,
high quality image data stored in the database 50b of the server
50a are compressed as a divided form and stored. The image data are
transmitted to the client system 52 through the network 51 only for
parts requested by a client, then compression of the image data is
released in the client system real time, and displayed on the
screen window 55 via the main memory unit 53 and the video buffer
54. Accordingly, in the system and method of the present invention,
even if capacity of a memory in a client system is less or network
bandwidth is less, information requested by a client is displayed
real time.
[0032] In the present invention, network includes all means in
which not only wire Internet or wireless Internet but also all
kinds of intranets and at least two electronic media are connected
for communication. Hereinafter, network will be explained mainly
about Internet.
[0033] High Quality Image Data
[0034] High quality image data according to the present invention
is a special format which fast displays huge image through network
in a client system. By using the format, huge image can be fast
displayed without delay of time, and fast searched. Also,
approximate information is searched by contracting the huge image
with layered data, and minute information is searched by magnifying
the image. The magnification and contraction processes also work
fast.
[0035] Digital information including huge image information is
converted by image converting system of the present invention by
the following main three steps.
[0036] converting huge image into multiple layered data according
to levels
[0037] dividing the huge image into a plurality of sub cells
[0038] compressing the image as divided cell units
[0039] To convert into high quality image data, general image files
such as BMP, GIF, PNG, JPG, etc. are used as original text
contents. Also, a text file such as PDF is converted into an image
file for use.
[0040] Original image files are converted into high quality image
data by steps shown in FIG. 4. First of all, a plurality of layers
sequentially structured from an image file are generated (60).
Then, the layered data are divided into a plurality of sub cells
(62), and compressed as divided cell units (64). Then, each index
is endowed to the compressed cells (66), and each cell is
integrated to be stored in database (68). The processes will be
explained in detail.
[0041] Generation of Layered Data
[0042] In the present invention, image data having a layered
structure are generated so as to provide high quality image in
which images of multimedia digital publication and etc. transmitted
real time on network are magnified or contracted fast and
accurately according to levels. That is, a plurality of data layers
converted with 1/2n, . . . , 1/4, 1/2, 1 times, etc. of an original
image are generated.
[0043] FIG. 5 is a schematic view showing layered data. As shown in
FIG. 5, high quality individual images are constituted by layers
according to displayed levels at the time of magnification or
contraction, and respective layers 70, 80, and 90 are used in
magnification or contraction steps. That is, in case of magnifying,
images are displayed from upper data 70 to bottom data 90 via
middle data 80. On the contrary, in case of contracting, images are
displayed in reverse order. Also, it is possible to change the
displayed screen discontinuously.
[0044] The number of layers in the layered structure are determined
by graphic user interface (GUI). In FIG. 5, data layers of three
steps are illustrated, but if graphic user interface can provide a
function of magnification or contraction with four steps, image
data are converted to have four layers.
[0045] Division of Huge Image
[0046] The generated data layers are divided into a plurality of
sub cells. By dividing the data, huge image is fast transmitted.
Division units of the huge image into a plurality of sub cells are
determined by a processing ability of a client system and a
transmittance speed on network. At this time, a number of sub cells
are determined within an optimum scope. Indexes are endowed to each
cell of the divided images, and the images are integrated by
positions or orders. The integrated cells exist as one file, but
only corresponding cells of the huge image are transmitted by a
client's request. According to this, a client can fast see his
wanted image.
[0047] Referring to FIG. 6, a process for displaying the divided
image data real time on network will be explained. Individual image
data 110 and 120 stored in database consist of sub cells
respectively. In Figure, Eij and Fij represent sub cells of i line
and j column.
[0048] As aforementioned, dividing image data into each sub cell
unit and then storing is determined by a processing ability of a
client system and a transmittance speed on network. At this time,
if a large number of sub cells are divided, a processing speed in a
central processing unit of a client system is down, and if few sub
cells are divided, a transmittance speed on network is down.
Therefore, it is important to divide the sub cells within an
optimum scope.
[0049] For example, supposing that screen display resolution is
1024.times.768 pixel, images displayed on a screen are divided into
5 horizontal sub cells and 4 vertical sub cells. The cells divided
at an optimum condition prevent delay in a transmitting process or
in a display process, and transmit image fast.
[0050] The divided sub cells are compressed, and endowed with
indexes, so that positions and coordinates etc. in an overall image
are recorded. Then, the sub cells are integrated into one file and
stored in database.
[0051] Compression of the Divided Image Data
[0052] High quality image data according to the present invention
are stored as a compressed form so as to improve a transmittance
speed.
[0053] It is preferable to compress data into each divided sub cell
unit. At this time, compression technique such as widely known
JPEG, GIFE are used. Each sub cell can be compressed with a same
method independently, or compressed with different methods. For
example, in case of data having a figure and a picture together,
GIF compression is used at the figure and JPEG compression is used
at the picture. By doing so, it is possible to improve compression
efficiency of an image.
[0054] The compressed sub cells are integrated according to orders
and positions, and are endowed with indexes respectively, then
stored in database. The indexes can include not only base
information of sub cells but also additional information relevant
to the sub cells. A server system is accessed to the indexes and
selects sub cells of a wanted image, thereby fast transmitting.
[0055] Transmittance of the Divided Image
[0056] If the client system requests special image information (for
example, click of a special item in a graphic user interface
circumstance, or move of a view point), a server system selects
only sub cells relevant to the client's request information in
image data stored in database and transmits the sub cells to the
client system.
[0057] For example, in case that a client requests special
information (110a) among one individual image data 110, only
relevant sub cells (E11, E21, E12, E22) are transmitted on network
(130) since sub cells of the individual image data are E11, E21,
E12, and E22. Also, the client system releases compression of the
transmitted sub cells in a central processing unit (compression
will be later explained), and displays only a displayed part 110a
in a display unit through a main memory unit.
[0058] Meanwhile, in case that the client system requires
information included in at least one individual image, sub cells
are transmitted by the following method. In FIG. 6, if the client
requests another special part 120a, the server system transmits sub
cells relevant to the part 120a among the two individual image data
110 and 120 to the client system, the sub cells, E33 and E34
included in the first image data 110 and F13 and F14 included in
the second image data 120. The client system releases compressions
of the transmitted sub cells in a central processing unit, and
displays only displayed part 120a in a display unit through a main
memory unit (140).
[0059] Once individual image data are divided into sub cells and
only requested cells by a client among the divided sub cells are
transmitted, huge image can be fast transmitted and displayed, even
if capacity of a main memory unit in the client system is less, a
processing ability of a main processing unit is less, or data
transmitting speed on network is low (that is, bandwidth of
transmittance line path on network is less).
[0060] Client/Server Model
[0061] High quality image data generated from the image converting
system can be displayed with just less memory and less calculation
of a main processing unit when a client system receives an image
file. The reason is why only required parts among sub cells divided
from huge image data are selected, transmitted, and displayed. The
larger original text image size (information amount) is and the
more the number of layers is, the more advantage is obtained.
[0062] The present inventors applied the advantage to the
client/server model in which network such as Internet line is used
and developed a powerful image providing solution. Accordingly, in
the present invention, at best utilized is display ability of a
client system having limitation in transmitting data on network
(that is, bandwidth), storing for the transmitted data, and
processing the data, thereby providing huge image real time.
[0063] A server system is connected to image database for storing
high quality image data and additional information database for
storing additional information, thereby providing information
requested by a client system real time. Like the transferring
system 12 in FIG. 1, the server system can include an independent
system for selecting required information from database and
transmitting to the client system at an inner side and can include
database together. On the other hand, image database and additional
information database can be constituted as additional database or
exist in another system.
[0064] A client system includes a central processing unit, a memory
unit, a display unit, and a browser for connecting to each server
through network. Once the client system is connected to the server
for transferring high quality image data according to the present
invention on network, the client system automatically receives a
client program for processing the high quality image data.
[0065] The client program provides various graphic user interfaces,
fast receives various contents provided from the server, and
displays in the client system. FIG. 7 is a schematic view showing
one embodiment of a graphic user interface. In FIG. 7, a graphic
user interface consists of a function button region 201, a section
menu and search region 202, and an image display region 203. The
user interface can have various constructions and forms according
to kinds of transmitted image data and user's convenience.
[0066] High quality image data according to the present invention
are applied to the client/server model, so that huge image
information is transmitted on network fast and efficiently and
displayed in the client system.
[0067] In the present invention, contrary to the related PDF
service and JPEG image providing solution where an overall image
file is transmitted, only a request part by a client system is
transmitted and displayed real time, thereby having a more
excellent performance. Also, since images are fast magnified or
contracted according to levels by a layered data structure, an
efficient search of image information is possible. That is, it is
possible to transmit, display and search image information real
time by image streaming.
[0068] In each index of high quality image data, not only
information regarding to sub cells but also additional information
are recorded. The additional information includes moving image,
text, sound, web page information regarding to each sub cell.
Therefore, if the server system transmits the additional
information to the client system with the image data, a user of the
client system can receive information of the moving picture, text,
web page, etc, together with image.
[0069] Information Request by a Client
[0070] It is general for an Internet user to search image by moving
a view point shown on a screen of a display unit such as a monitor
of a client system. Image information requested by a client system
exists in a server system, so that the client system has to request
transmittance of corresponding information to the server.
[0071] The process works by a series of streaming packet defined in
advance, and is performed by a client program already transmitted
to the transmittance system in the server system and the client
system. The process will be explained in detail.
[0072] A user is connected to a server on network in a client
system. To the first connected user, a client program is
automatically transmitted from a server at the time of connection
(to the user already connected, the client program needs not to be
transmitted), and the client program makes the user search
information requested by the server by providing graphic user
interface in the client system.
[0073] The user requests image information and image level change
in the interface provided by the client program. The process is
shown as a click for items and icon on the interface displayed on a
screen.
[0074] By the process, a request by the client system is
transmitted to the server on network. The server receives the
request and searches sub cells corresponding to a part requested by
the client system, then transmits one by one real time.
[0075] In the client system, compressions of sub cells (image tile)
transmitted from the server are released real time in a central
processing unit, and the sub cells are displayed on a screen via a
main memory unit and a video buffer. Accordingly, a screen is
immediately displayed without delay of image processing in the
client system.
[0076] If the user moves a view point to a new region on interface
of a monitor screen or changes an image level, the client program
transmits information request for the new image region or image of
different level to the server.
[0077] FIG. 8 is a schematic view showing that a screen is renewed
by transmitting image information according to the present
invention. If display data 110a and 120a transmitted from database
of the server are displayed on a screen 250 and the screen is moved
(260), image data for a new region 260a are transmitted from the
database of the server and integrated with the original display
data 110a or 120a in the client system. The integrated data
constitute a new integrated image (260a and 110a or 260a and 120a)
and are displayed on a screen window. Accordingly, screen change is
not delayed or discontinuous, rather a continuous display like
moving image is possible.
[0078] Providing Additional Information
[0079] In a state that the server selects image data from database
according to a request of the client system, if additional
information is included on index, the additional information is
transmitted to the client system with image data.
[0080] The additional information is stored in additional
information database of the server. In the database, a location
(that is, image data which will be displayed with the additional
information), kinds, and styles of the additional information (for
example, in case of text information, color, font, and in case of
moving image information, image path) are stored. The additional
information can be generated through a separate tool and can be
input by a hand work.
[0081] It is preferable to manage the additional information
provided with high quality image according to the present invention
through a separate file. The file is defined as MAP file in the
present invention. The additional information management file
consists of a script language, and contains a position and an
attribute of the additional information on the basis of resolution
of high quality image.
[0082] For example, in case of providing moving image of Abc.mpg in
500.times.500 position of 1000.times.1000 high quality image, if an
image file name is Abc.IPQ, Abc.MAP having the same file name are
generated and defined as follows.
[0083] Movie 500, 500 Abc.mpg
[0084] The additional information file (Abc.mpg) and the management
file (Abc.MAP) are stored in additional information database. If
image information requested by the client is Abc.IPQ, the server
connects the image information with Abc, MAP and transmits to the
client system with Abc.mpg.
Preferred Embodiments
[0085] Hereinafter, real time service of multimedia digital
publication will be explained in detail.
[0086] FIG. 9 is a flow chart showing a real time service process
of a multimedia digital publication according to the present
invention.
[0087] In a data collecting step (310), individual image data and
additional information data which will be constituted as real time
integrated data are collected. The individual image data are
generally interactive one another. Examples of the individual data
include data which scanned each side of a newspaper, data which
scanned each side of a magazine, image data converted in PDF file,
and image data directly converted from typesetting system, etc.
Also, the additional information data which will be used in the
step includes moving image file, sound file, another image file,
text information, and web page address, etc.
[0088] A manufacturing step (320) is a step for converting data
collected in the data collecting step into individual high quality
image data and for connecting with additional information data.
[0089] A file converted from PDF and from typesetting system is
converted to high quality image file according to the present
invention, and a newspaper and a magazine are scanned to be
manufactured as an image file, thereby generating high quality
image. In the step, methods such as the aforementioned data layer
generation, image division, and compression, etc. are used.
[0090] Also, in the step, a search keyword necessary to an image
search is extracted. The keyword can be a theme word regarding a
headline in case of a newspaper. Then, determined is whether
individual image, search keyword, and additional information
collected in the data collecting step 310 are interactive one
another or not. In the case, the additional information can be edit
by hand work or another tool (editing tool), or data relevant one
another are connected to be integrated.
[0091] Then, respective data are stored in high quality image
database and additional information database (330).
[0092] In a transmitting step (340), at the time of transmitting
information according to a request of a client on Internet network,
only data display region 110a or 120a are transmitted.
[0093] In a displaying step (350), the transmitted data display
region is displayed on a screen window via a central processing
unit, a main memory unit, a video buffer, etc. in the client
system.
[0094] As shown in FIG. 9, the server reads data stored in database
when the client requests individual image and additional
information and transmits the data to the client through Internet.
At this time, in case that image data requested by a client are on
several individual images, corresponding data (that is, each sub
cell) are transmitted real time, and integrated in the client
system to constitute as one image. The additional information
selects corresponding information in additional information
database and transmits with image data real time as a streaming
form.
[0095] FIG. 10 is a screen capture showing an embodiment of GUI of
a digital newspaper according to the present invention.
[0096] A function button region (corresponding to 201 of FIG. 7)
includes a tool for selecting a newspaper according to kinds, a
tool for selecting a page of the selected newspaper, a tool for
selecting a part of displayed digital newspaper, a tool for
displaying the selected region, and a clipping function for storing
the selected region or individual image as another file.
[0097] In section menu and searching region (202 in FIG. 7),
contents of a newspaper are classified into an entire headline,
politics, economy, society, culture, international, sports,
entertainment, region, and serials, etc., and corresponding
individual image information is included. The searching region
consists of a part for inputting a search keyword and a part for
displaying a search result. The search result is displayed at a
bottom of the section menu as a list form.
[0098] In image display region (203 of FIG. 7), selected individual
image and real time integrated image are displayed.
[0099] High quality newspaper or magazine image transmitted from
the database of the server can be displayed with various methods
besides the methods shown in the preferred embodiments.
[0100] Meanwhile, if a user moves a view point along displayed
images by using a mouse, only renewed region is transmitted from
the server and displayed. Even if the user moves high quality
digital image to any directions, image data of the new region are
transmitted real time without delay in a transmitting process and
displayed on a screen. Also, if the user clicks a wanted part with
a mouse, the part can automatically move to a center of a
screen.
[0101] Image magnification or contraction function is performed by
locating a mouse cursor to a wanted part and clicking. The
magnification or contraction can be performed by a layer unit step
by step, or can be performed at one time from the highest step (70
of FIG. 5) to the lowest step (90 of FIG. 5). At this time, the
renewed data are displayed by the same method shown in FIG. 8. In
case of magnifying or contracting image, various effects can be
simultaneously realized by using contents such as sound, image,
text, and flash animation, etc.
[0102] In case that hyper-linked additional information exists at a
special position of image displayed from a display unit of the
client system, the corresponding information is displayed on a
screen real time. At this time, the additional information can be
displayed on a current window, or on a new window. Additional
information data that will be used with high quality image includes
moving image file, sound file, flash animation, another high
quality image file, text information, and web page address, etc.
FIG. 11 shows a real time service of a magazine corresponding to
one of multimedia publications. Alike the aforementioned
embodiments, various additional information can be provided with
high quality image data. Also, in case that another image is
requested besides the information shown on a screen, a screen is
renewed real time and displayed in the client system.
[0103] According to the present invention, high quality image data
are provided real time without extending network bandwidth and
increasing capacity of a main memory device. Especially, huge image
information is provided as high quality image data without
extending a client system and delaying time.
[0104] Also, in the present invention, possible is real time
service of high picture quality multimedia digital publication, and
image data and relevant additional information data are provided
through a graphic user interface, so that a user can easily obtain
various information. Also, wanted information is fast searched, and
same resolution is maintained at the time of magnifying a screen. A
real time service of high picture quality multimedia digital
publication can be applied to all publications issued periodically,
so that various on-line services are possible.
[0105] As the present invention may be embodied in several forms
without departing from the spirit or essential characteristics
thereof, it should also be understood that the above-described
embodiments are not limited by any of the details of the foregoing
description, unless otherwise specified, but rather should be
