Patent ID: 8072659

Claim:
A color processor comprising: a conversion source color data acquiring part for acquiring conversion source color datasets in a first color space; a gamut storage for storing a gamut; a determining part for determining whether or not each of the conversion source color datasets acquired by the conversion source color data acquiring part exists in the gamut stored in the gamut storage; a first color conversion processor for performing color conversion processing on each of conversion source color datasets A included in the conversion source color datasets by use of a color conversion characteristic model that defines correspondence between colors in the first color space and colors in a second color space which is a destination for the color conversion processing, the conversion source color datasets A being determined to exist in the gamut by the determining part; and a second color conversion processor for performing color conversion processing on each of conversion source color datasets B included in the conversion source color datasets by use of color conversion correspondence that is obtained by performing the color conversion processing on the conversion source color datasets A by the first color conversion processor, the conversion source color datasets B being determined not to exist in the gamut by the determining part, the second color conversion processor including a hue angle calculating portion for extracting datasets from the conversion source color datasets A that have a same lightness as the conversion source color datasets B, and calculating a hue angle with respect to each of the conversion source color datasets B and the extracted conversion source color datasets A.
