Abstract

Color matching is performed in a network system using a communication device which communicates with a network server storing plural device profiles and color management modules. A selection device selected a device profile, based on kinds of the plural device profiles inputted through the communication device, and a controller downloads the selected device profile and a color management module from the network server. A color matching processor performs a color matching process on input image data by using the downloaded device profile and the downloaded color management module.

Claims

1. An image processing apparatus connected to a network server through network, comprising:

a communication unit for communicating with said network server;

a reception unit for receiving from said network server a list of device profiles stored in said network server, by using said communication unit;

a selector for selecting from said list a desired destination device profile, based on user'"'"'s instructions;

a transmitter for requesting the selected destination device profile to said network server and downloading the selected device profile and requesting to said network server a color management module according to information described in the downloaded destination device profile and downloading the color management module from said network server by using said communication unit; and

a processor for performing a color matching process by using a source device profile and the downloaded destination device profile on a basis of the downloaded color management module.

2. An apparatus according to claim 1, wherein

both a source profile and a destination profile are used in the color matching process, and the downloaded device profile is set as the source profile,

said network server stores the plural different color management modules, and

the downloaded color management module is selected from among the plural color management modules stored in said network server, based on information of the destination profile.

3. An apparatus according to claim 1, wherein the device profile is calibrated by using a calibration program downloaded from said network server.

4. An apparatus according to claim 3, wherein the calibrated device profile is transferred to said network server by said communication means.

5. An apparatus according to claim 4, wherein the network server stores the device profile and the calibrated device profile independently of each other.

8. An apparatus according to claim 1, further comprising input means for inputting an input image constituted by an image file and a text file,

wherein said color matching process means performs the color matching process on data of the image file but does not perform the color matching process on data of the text file.

6. An image processing method for an image processing apparatus connected to a network server through a network, said method comprising:

a communication step of communication with the network server;

a reception step of receiving from the network server a list of device profiles stored in the network server, through said communication step;

a selection step of selecting from the list a desired destination device profile, based on user'"'"'s instructions;

a transmission step of requesting the selected destination device profile to the network server and downloading the selected device profile, and requesting to said network server a color management module according to information described in the downloaded destination device profile and downloading the color management module from said network server by using said communication step; and

a color matching process step of performing a color matching process by using a source device profile and the downloaded device destination device profile on a basis of the downloaded color management module.

7. A storage medium which stores a computer readable program for realizing an image processing method for an image processing apparatus connected to a network server through a network, said method comprising:

a communication step of communicating with the network server;

a reception step of receiving from the network server a list of device profiles stored in the network server, through said communication step;

a selection step of selecting from the list a desired destination device profile, based on user'"'"'s instruction;

a transmission step of requesting the selected destination device profile to the network server and downloading the selected device profile, and requesting to said network server a color management module according to information described in the downloaded destination device profile and downloading the color management module from said network server by using said communication step; and

a color matching process step of performing a color matching process by using a source device profile and the downloaded destination device profile on a basis of the downloaded color management module.

9. A network server which is connected through a network to a client performing color matching, comprising:

communication means for communicating with said client;

storage means for storing device profiles and a color management module;

first transmission means for transmitting, to said client, a list of device profiles stored in said network server by using said communication means;

first reception means for receiving, from said client, information representing a desired device profile selected from said list of device profiles, by using said communication means;

second transmission means for transmitting, to said client, said selected device profile; and

second reception means for receiving, from said client, information representing a desired color management module, said color management module corresponding to information described in the transmitted device profile.

10. An image processing method for a network server connected through a network to a client performing color matching, said method comprising:

a communication step of communicating with said client;

a storage step of storing device profiles and a color management module;

a first transmission step of transmitting, to said client, a list of device profiles stored in the network server through said communication step;

a first reception step of receiving, from said client, information representing a desired device profile selected from the list of device profiles, through said communication step;

a second transmission step of transmitting, to said client, the selected device profile; and

a second reception step of receiving, from said client, information representing a desired color management module, said color management module corresponding to information described in the transmitted device profile.

11. A storage medium which store a computer readable program for realizing an image processing method for a network server connected through a network to a client performing color matching, said method comprising:

a communication step of communicating with said client;

a storage step of storing device profiles and a color management module;

a first transmissions step of transmitting, to said client, a list of device profiles stored in the network server through said communication step;

a first reception step of receiving, from said client, information representing a desired device profile selected from the list of device profiles, through said communication step;

a second transmission step of transmitting, to said client, the selected device profile; and

a second reception step of receiving, from said client, information representing a desired color management module, said color management module corresponding to information described in the transmitted device profile.
