发明名称 Color processing apparatus and method
摘要 It is desired to adopt gamut mapping using a color appearance space in the processing system of an ICC profile. Upon generating an LUT complying with the ICC profile format, when CIEL*a*b* values are converted into CIEXYZ values, and the XYZ values are converted into color appearance space values using color appearance conversion formulas, a point which can be converted and becomes a nearest neighboring point for a point that satisfies a predetermined condition is retrieved, and corresponding color appearance space values are calculated. The obtained color appearance space values are mapped on a predetermined device gamut.
