COLOR GAMUT MAINTAINING SYSTEM AND METHOD

The present disclosure provides a system and a method for retaining color gamut, the color gamut of an image which is transmitted from a first color gamut to a second color gamut is retained by generating a standard color comparison table of image colors in the first color gamut and image colors in the second color gamut. The system includes: a first converting module, configured to convert a color system of the first color gamut into a first converted color gamut; a second converting module, configured to convert a color system of the second color gamut into a second converted color gamut; a coordinate point mapping module, configured to calculate a coordinate point in the second converted color gamut corresponding to each coordinate point in the first converted color gamut according to a corresponding algorithm; a correspondence table generating module, configured to generate a correspondence table of the first converted color gamut and the second converted color gamut; a standard color comparison table generating module, configured to generate the standard color comparison table according to the correspondence table. The present disclosure can maintain the output results of the images displayed on different displays, to retain the color gamut, improve image processing speed, and reduce consumption of CPU.
