Abstract:
A color processing apparatus includes an image signal acquisition section, a color component preservation section, a first color conversion section, a color gamut compression section and a second color conversion section. The image signal acquisition section acquires an image signal including an input color signal having predetermined color components. The color component preservation section preserves at least one of the color components of the input color signal as a preserved color component. The first color conversion section converts the input color signal into an intermediate color signal belonging to a first color space. The color gamut compression section performs a color gamut compression for the intermediate color signal using color components of the intermediate color signal and the preserved color component, to generate a compressed color signal. The second color conversion section that converts the compressed color signal into an output color signal belonging to a second color space.
