`AND IMAGE COLOR CORRECTION
`APPARATUS
`
`BACKGROUND OF THE INVENTION
`This invention relates to color image transfer techniques
`for distributing or transferring a color image and an object
`for preparing a color image over a network and in particular
`to an image transfer apparatus, an image transmitter, a
`profile information transmitter, an image receiver/
`reproducer, a Storage medium, an image receiver, a program
`transmitter, and an image color correction apparatus which
`enable a receiving party to display an image with original
`image colors held.
`AS information processing and communication technolo
`gies have become advanced, various techniques for connect
`ing various devices for handling color image information,
`Such as Scanners, facsimiles, and color printers, and trans
`ferring color images between the devices have been pro
`posed.
`By the way, the transferred color image is reproduced by
`reproduction means Such as a display device of the receiving
`party. At the time, the characteristics of the image input
`device at the transmitting party (for example, a Scanner) do
`not necessarily match those of the reproduction means at the
`receiving party (for example, a color printer), thus it
`becomes necessary to execute color conversion in the color
`image transfer process.
`Disclosed as one of the color conversion techniques, for
`example, in the Unexamined Japanese Patent Application
`Publication Nos. Hei7-203175 and 7-312694 is a technique
`wherein the transmitting party has a color conversion func
`tion and the receiving party transferS profile information to
`the transmitting party, which then executes color conversion
`and transmits the resultant image to the receiving party,
`which will be hereinafter referred to as first prior art. The
`profile information is information defining the characteris
`tics of a color Space used to describe colors used in color
`image information; generally, color Spaces defined based on
`perception of human beings, such as CIE XYZ and CIE
`L*a*b*, and information describing the mathematical rela
`tionship between the color Spaces of color image informa
`tion are used. In addition to the first prior art, a technique
`wherein the receiving party has a color conversion function
`and the transmitting party transfer profile information and an
`image to the receiving party, which then executes color
`conversion, which will be hereinafter referred to as second
`prior art, is disclosed in the Unexamined Japanese Patent
`Application Publication No. Hei 7-312694.
`By the way, to apply the conventional techniques
`described above to an image transfer apparatus using a
`large-scale network environment Such as the Internet, an
`undesired situation occurs on efficiency of communication
`lines or administration of the system. That is, if the first prior
`art is applied, the color conversion function at the transmit
`ting party must deal with color conversion requests from a
`large number of receivers. Thus, the transmitting party
`requires a large processing capability and if it has an
`insufficient processing capability, processing takes time. On
`the other hand, if the Second prior art is applied, when the
`receiving party receives images from a number of
`transmitters, even if the received images have the Same color

`Space, profile information needs to be transmitted each time
`the transmitting party changes. Thus, fruitleSS communica
`tion becomes necessary and efficient use of the communi
`cation line capacity cannot be made. If either of the first and
`Second prior arts is applied, it becomes necessary to transfer
`profile information between the transmitting and receiving
`parties each time one image transfer is executed. Thus, it
`cannot be avoided to bear the communication costs to
`transfer the profile information.
`SUMMARY OF THE INVENTION
`It is therefore an object of the invention to provide an
`image transfer apparatus, an image transmitter, a profile
`information transmitter, and an image receiver/reproducer
`whereby color image information or object information for
`preparing color image information can be transferred with
`out putting a large load on a specific transmitter or executing
`fruitleSS communication and the receiving party can repro
`duce an image with original image colors held.
`Means for solving the problems will be discussed with
`reference to FIG. 1.
`First, an image transfer apparatus of aspect 1 is provided
`according to the configuration shown in FIG. 1 and com
`prises:
`a profile Server 1 being connected to a network for Storing
`profile information for a color correction made to color
`image information or color image information prepared
`from object information and outputting profile infor
`mation in response to a call from an image display
`device 3 (described later);
`an image server 2 (image transmission means) for trans
`mitting profile Specification information specifying the
`profile information corresponding to the color image
`information or the object information together with the
`color image information or the object information;
`an image display device 3 (image reception and repro
`duction means) comprising reception means 30 for
`receiving the color image information or the object
`information and the profile Specification information
`transmitted by the image transmission means, call
`means 34 for calling profile information Specified by
`the profile Specification information received by the
`reception means from the profile Storage means, color
`correction means 35 using the profile information for
`making a color correction to the color image informa
`tion or color image information prepared from the
`object information, and reproduction means 36 for
`reproducing the color image information to which a
`color correction has been made by the color correction
`CS.
`According to the image transfer apparatus, the image
`Server 2 is released from the load for transferring profile
`information itself as well as the color correction load and can
`raise processing efficiency accordingly. Since the profile
`information itself is not transferred, congestion of the com
`munication line connected to the image Server 2 can be
`relieved. On the other hand, the image display device 3 can
`receive necessary profile information from the profile Server
`1 based on the profile specification information provided by
`the image Server 2, So that an image color correction can be
`made without a hitch.
`The profile information may be information defining a
`color Space used to describe the color image information or
`color image information prepared from the object informa
`tion. (Aspect 2)
`The profile Specification information may be any if it can
`Specify necessary profile information; preferably, it is loca

`tion information specifying a location of Storage means on
`the network where the profile information exists and a
`Storage location of the profile information in the Storage
`means for the image display device 3 to obtain necessary
`profile information promptly. (Aspect 3)
`The invention of aspects 4 to 7 provides main components
`making up the image transfer apparatus.
`That is, an image transmitter of aspect 4, which is
`provided as the image Server 2 in FIG. 1, comprises trans
`mission means 20 for transmitting through a network, color
`image information or object information for preparing color
`image information and profile Specification information
`(location information in the example in FIG. 1) Specifying
`profile information for a color correction made to the color
`image information or color image information prepared
`from the object information.
`A profile information transmitter of aspect 5, which is
`provided as the profile server 1 in FIG. 1, comprises profile
`Storage means 10 for Storing profile information for a color
`correction made to color image information or color image
`information prepared from object information; and
`communication control means 11 for transmitting the
`profile information to a calling party when the profile
`information is called through a network.
`An image receiver/reproducer of aspect 6, which is pro
`Vided as the image display device 3 in FIG. 1, comprises
`reception means 30 for receiving color image information or
`object information for preparing color image information
`and profile Specification information Specifying profile
`information for a color correction made to the color image
`information or color image information prepared from the
`object information, Sent through a network;
`call means 34 for calling through the network, profile
`information corresponding to the profile specification
`information received by the reception means;
`color correction means 35 using the profile information
`for making a color correction to the color image
`information or color image information prepared from
`the object information; and
`reproduction means 36 for reproducing the color image
`information to which a color correction has been made
`by the color correction means.
`The invention of aspect 7 introduces the So-called cache
`Storage technique for raising the processing efficiency of the
`image reproducer 3. That is, as shown in FIG. 1, the image
`display device 3 comprises:
`reception means 30 for receiving color image information
`or object information for preparing color image infor
`mation and profile specification information (location
`information in the example in FIG. 1) Specifying profile
`information for a color correction made to the color
`image information or color image information prepared
`from the object information, Sent through a network;
`registration means 31 for registering profile information
`received through the network together with the profile
`Specification information for Specifying the profile
`information;
`determination means 32 for determining whether or not
`the same information as the profile Specification infor
`mation received by the reception means is registered in
`the registration means,
`getting means 33 for getting profile information corre
`sponding to the profile Specification information from
`the registration means if a determination that the same
`information as the profile Specification information
`received by the reception means is registered in the
`registration means is obtained from the determination
`means,

`call means 34 for calling profile information through the
`network if a determination that the Same information as
`the profile Specification information received by the
`reception means is not registered in the registration
`means is obtained from the determination means,
`color correction means 35 using the profile information
`obtained by the getting means or the call means for
`making a color correction to the color image informa
`tion or color image information prepared from the
`object information; and
`reproduction means 36 for reproducing the color image
`information to which a color correction has been made
`by the color correction means.
`According to the image display device 3, only if new
`profile Specification information not received in the past is
`received, the corresponding profile information is called
`through the network. If the same information as already
`received profile Specification information is received, the
`profile information received in the past is reused. Therefore,
`the frequency calling profile information through the net
`work can be lessened, fruitleSS communication can be
`prevented, and the processing efficiency of the image display
`device 3 can be raised.
`According to the invention of aspect 8, as shown in FIG.
`11, there is provided a storage medium 501 for storing data
`accessed by a program executed by a computer 500 and
`having a predetermined data Structure in a format that can be
