Patent ID: 7612782

Claim:
A color conversion matrix creating device, comprising: a first conversion matrix creating unit for determining a first conversion matrix (M LCD ) for color conversion between a color space of a display device and a reference color space; a first calculating unit for, based on the first conversion matrix (M LCD ), calculating first color values on the reference color space which correspond to predetermined colors on the color space of the display device; a second conversion matrix creating unit for determining a second conversion matrix (M tgt ) for color conversion between a prescribed target color space and the reference color space; a second calculating unit for, based on the second conversion matrix (M tgt ), calculating second color values on the prescribed target color space which correspond to the predetermined colors; an arithmetic unit for, based on the first color values and the second color values, determining third color values on a new target color space which correspond to the predetermined colors; a third conversion matrix creating unit for, based on the third color values, determining a third conversion matrix (M new ) for color conversion between the new target color space and the reference color space; a color conversion matrix creating unit for, based on the first conversion matrix (M LCD ) and the third conversion matrix (M new ), determining a color conversion matrix (M) for color conversion between the color space of the display device and the new target color space; and a color adaptation correction matrix creating unit for determining a color adaptation correction matrix (M col ) on the basis of a white point in the color space of the display device and a white point in the prescribed target color space; wherein the first conversion matrix creating unit is configured to create the first conversion matrix (M LCD ) by using the color adaptation correction matrix (M col ).
