摘要

PROBLEM TO BE SOLVED: To perform accurate color conversion and color adjustment that suit sensations of a human being, and to improve consistency, compatibility and affinity to a conventional device or system.

SOLUTION: A color conversion device includes: a lattice point arrangement part for generating a radial color conversion table by equally arranging lattice points as correspondence of RGB values of an input device and CMYK values of an output device radially from a prescribed achromatic color axis between the input device expressed by three values of RGB and the output device expressed by four values of CMYK; and a color conversion table reorganization processing part for generating a cubic lattice type color conversion table in which the lattice points form a cubic lattice by laminating hue layers comprising the same hue surface and the complementary color hue surface thereof in the radial color conversion table in a hue order.
