摘要

A color image processing apparatus comprises a plane signal conversion section which converts a color space expressed by an input color signal image to a plane and generates a plane signal; a chroma identification section which identifies a chroma of the color image based on the generated plane signal and generates a chroma identification signal; a hue area identification section which identifies a hue area in the color image signal based on the generated plane signal and generates a hue area identification signal; and a color conversion section which executes color conversion of the color image signal based on the generated chroma identification signal and the hue area identification signal.
