Patent ID: 7990575

Claim:
A color processing apparatus comprising: a setting section, arranged to set a correction region of an input gamut in accordance with a chroma of a specific color point of the input gamut, and set a correction region of an output gamut in accordance with a chroma of a specific color point of the output gamut, wherein the specific color points are either white points or black points; a gamut corrector, arranged to correct the correction region of the output gamut based on the chroma of the specific color point of the output gamut so that the specific color point of the output gamut is mapped on a point on a lightness axis of a color space; a data corrector, arranged to correct input color data in the correction region of the input gamut so that the specific color point of the input gamut based on the chroma of the specific color point of the input gamut is mapped on a point on the lightness axis of the color space; a mapping section, arranged to map the corrected color data into the output gamut having the correction region corrected by the gamut corrector; and an inverse corrector, arranged to perform inverse correction of correction by the gamut corrector to the mapped color data based on the correction region of the output gamut, wherein the chroma indicates a distance between the lightness axis of the color space and the specific color point, and the correction region is increased from a maximum or minimum lightness point of the input or output gamut in accordance with an increase of the distance until the distance reaches a predetermined value.
