Abstract
A satisfactory simulation image is provided regardless of an output object observation environment and a display object observation environment. The image processing method for simulating an image output from an image output device in advance includes the steps of: performing a color correction process in accordance with an output object observation environment when an image output from the image output device is observed; and performing a color correction process on image data on which the color correction has been performed in accordance with an output object observation environment and a display object environment when a simulation image is observed.
Claims10
An image processing method of performing a correction process based on an observation environment by using a color management module, comprising:
- an input step, of inputting device discrimination information and observation environment information;
- a selection step, of, based on the device discrimination information, selecting a profile from a stored profile group, the profile having a public region and a private region, wherein, in the public region, conversion data indicating a relationship between a standard color space and a device color space is stored;
- a rewrite step, of rewriting the selected profile by rewriting color correction data described in the public region of the selected profile, based on the observation environment information;
- an addition step, of adding the rewritten profile to the profile group;
- and
- a performance step, of performing a color matching process on the image data by causing the color management module to use the profile data which corresponds to the device discrimination information.
An image processing method of performing a correction process based on an observation environment by using a color management module, comprising:
- an input step, of inputting device discrimination information and observation environment information;
- a selection step, of, based on the device discrimination information, selecting a profile from a stored profile group, the profile having a public region and a private region;
- an addition step, of adding observation environment correction data, which corresponds to said observation environment information, to the private region of profile data which corresponds to the device discrimination information;
- and
- a performance step, of performing a color matching process on the image data by causing the color management module to use the selected profile data,
- wherein the color matching process uses a conversion data, which indicates a relationship between a standard color space and a device color space, in the public region of said selected profile, and said observation environment correction data in the private region of said selected profile.
A computer program product embodying a program for implementing an image processing method of performing a correction process based on an observation environment by using a color management module, the program comprising:
- program code for an input step of, inputting discrimination information and observation environment information;
- program code for a selection step of, based on the device discrimination information, selecting a profile from a stored profile group, where the profile has a public region and a private region, wherein, in the public region of the profile data, conversion data indicating a relationship between a standard color space and a device color space is stored;
- program code for a rewrite step, of rewriting color correction data described in a public region of the selected profile, based on the observation environment information;
- program code for an addition step, of adding the rewritten profile to the profile group;
- and
- program code for a performance step, of performing a color matching process on the image data by causing the color management module to use the profile data which corresponds to the device discrimination information.
