Abstract

There is a method of executing color matching for image data obtained via a network using a profile of an input device embedded in image data received from a server, a profile of an output device selected by the user, and a color matching module (CMM) of the client. This processing method is suitable for distributed processing since the load on the server is light. However, since the CMM of the client is used, different color matching results may be obtained if clients use different CMMs. Furthermore, when the user has no CMM, color matching cannot be done. Hence, upon downloading an HTML document on the server designated by the user, the HTML document is interpreted by a WWW browser, and when the HTML document contains a link for downloading a CMM program, the CMM program is downloaded via the network.

Claims

1. An image processing apparatus for processing document data, which is downloaded via a network and which is set with an image link to image data, comprising:

an obtaining unit, arranged to download the document data from a server on the network;

a download unit, arranged to download a program of a color matching module, based on a file link included in the downloaded document data for downloading the program of the color matching module, to download the image data, based on the image link included in the downloaded document data, and to download an input profile linked to the image data, via the network;

an acquisition unit, arranged to acquire an output profile; and

a processor, arranged to execute a color matching process on the downloaded image data using the input and output profiles under control of the downloaded program of the color matching module.

2. The apparatus according to claim 1, wherein the document data is an HTML document.

3. The apparatus according to claim 1, wherein the program of the color matching module is described in an intermediate code format.

4. The apparatus according to claim 3, further comprising a translation unit, arranged to translate the program of the color matching module described in the intermediate code format into a native code format depending on an operating system or a microprocessor of said apparatus.

5. An image processing method of processing document data, which is downloaded via a network and which is set with an image link to image data, said method comprising the steps of:

downloading the document data from a server on the network;

downloading a program of a color matching module, based on a file link included in the downloaded document data for downloading it, via the network;

downloading the image data, based on the image link included in the downloaded document data via the network;

downloading an input profile linked to the image data, via the network;

acquiring an output profile; and

executing a color matching process on the downloaded image data using the input and output profiles acquired profile under control of the downloaded program of the color matching module.

6. The method according to claim 5, wherein the document data is an HTML document.

7. The method according to claim 5, wherein the program of the color matching module is described in an intermediate code format.

8. The method according to claim 7, further comprising the step of translating the program of the color matching module described in the intermediate code format into a native code format depending on an operating system or a microprocessor of an apparatus in which said image processing method is executed.

10. The method according to claim 5, wherein the color matching process is executed using the input profile related to the image data and the output profile related to a monitor connected to an apparatus in which said image processing method is executed, and wherein the step of downloading the image data includes the steps of:

determining the input profile of each of a plurality image data linked to the downloaded document data;

generating a profile list of determined input profiles; and

downloading the input profile based on the profile list.

13. The method according to claim 5, further comprising the step of controlling operation of said executing step in accordance with a user instruction.

9. A computer program for implementing an image processing method of processing document data, which is downloaded via a network and which is set with an image link to image data, said program comprising:

code for downloading the document data from a server on the network;

code for downloading a program of a color matching module, based on a file link included in the downloaded document data for downloading the program of the color matching module, via the network;

code for downloading the image data, based on the image link included in the downloaded document data, via the network;

code for downloading an input profile linked to the image data, via the network;

code for acquiring an output profile; and

code for executing a color matching process on the downloaded image data using the input and output profiles under control of the downloaded program of the color matching module.

11. An image processing method of processing document data, which is downloaded via a network and which is set with an image link to image data, said method comprising the steps of:

downloading a color matching module, based on a file link included in the document data for downloading it, via the network;

downloading the image data, based on the image link included in the document data, via the network; and

executing a color matching process on the downloaded image data using the downloaded color matching module and outputting the processed image data to an image output device,

wherein the color matching process is executed using a source profile related to the image data and a monitor profile related to a monitor connected to an apparatus in which said image processing method is executed, and

when the document data links to a plurality of image data, image data relating to a same source profile are subjected to the color matching process in series.

12. An image processing method of processing document data, which is downloaded via a network and which is set with an image link to image data, said method comprising the steps of:

downloading a color matching module, based on a file link included in the document data for downloading it, via the network;

downloading the image data, based on the image link included in the document data, via the network;

executing a color matching process on the downloaded image data using the downloaded color matching module;

reducing an image size of the downloaded image data;

controlling whether the reduced image data is subjected to the color matching process or not; and

outputting the reduced image data to an image output device.
