Patent ID: 7982927

Claim:
A color processing apparatus comprising: a first color signal obtaining unit that obtains a first color signal in a first color space; a color conversion unit that converts the first color signal in the first color space obtained by the first color signal obtaining unit into a second color signal in a second color space according to a color conversion characteristic associating a color signal in the first color space with a color signal in the second color space; a calculation unit that calculates a distance of the first color signal to an outer boundary of a color gamut in the first color space; and a color conversion characteristic generation unit that generates the color conversion characteristic to be used by the color conversion unit to make the conversion, the color conversion characteristic generation unit changing a generation condition of the color conversion characteristic according to the distance of the first color signal calculated by the calculation unit, wherein the color conversion characteristic generation unit assigns weight to a plurality of color data pairs, the color data pair consisting of each of a plurality of color data sets in the first color space and a corresponding one of a plurality of color data sets obtained by measuring, in the second color space, a color of an image formed from each of the plurality of color data sets in the first color space, the color conversion characteristic generation unit generates the color conversion characteristic according to the plurality of color data pairs to which the weight has been assigned, and changes the weight that is assigned to the plurality of color data pairs according to the distance calculated by the calculation unit when the color conversion characteristic is generated.
