Abstract
The present disclosure provides a system and a method for retaining 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.
