Abstract:
1. A color processor comprising: a conversion source color data acquiring part that acquires a conversion source color dataset in a first color space; a color data pair acquiring part that acquires color data pairs each composed of a color dataset in the first color space and a color dataset in a second color space that is a conversion destination color space, the color dataset in the first color space and the color dataset in the second color space being both used to calculate a color conversion characteristic model specifying a correspondence between a color in the first color space and a color in the second color space; where S is the evaluation value, σ 2 second color space is a degree of dispersion of the color dataset in the second color space from a mean value coordinate point in the surrounding region for the second color space and σ 2 first color space is a degree of dispersion of the color dataset in the first color space from a mean value coordinate point in the surrounding region for the first color space, the color conversion characteristic model calculator adjusting the weight to be assigned to the color dataset in the first color space according to the evaluation value, which is associated with the coordinate component, calculated by the evaluation value calculator, when calculating the color conversion characteristic model.
