Patent ID: 7079280

Claim:
A color conversion definition creating method of creating a color conversion definition defining an association between a color in a color representation area of an arbitrary device mediating between a color image and image data and a color in a color representation area of a predetermined target device mediating between a color image and image data, said color conversion definition creating method comprising: a definition creating step of creating a first color conversion defining an association between a color in a predetermined reference color representation area wherein an area difference between the reference color representation area and the color representation area of the arbitrary device is smaller than an area difference between the reference color representation area and the color representation area of the target device, and a color in the color representation area of the arbitrary device; and a definition combination step of combining a second color conversion definition created beforehand defining an association between a color in the reference color representation area and a color in a color representation area of the target device, with the first color conversion definition created in said definition creating step.
