PROBLEM TO BE SOLVED: To perform color conversion as expected by an operator at the time of color converting a specified color to the other specified color. SOLUTION: This processor is provided with a plane signal transformation part 102 for transforming a color space indicated by inputted color image signals to a plane and generating plane signals, a saturation identification part 103 for identifying the saturation of the color image signals based on the generated plane signals and generating saturation identification signals, a hue area identification part 104 for identifying the area of a hue in the color image signals based on the generated plane signals and generating hue area identification signals and a color conversion part 105 for performing the color conversion of the color image signals based on the generated saturation identification signals and the hue area identification signals generated by the hue area identification means.
