摘要
A color distance measurement apparatus includes: a first transformation section that transforms first color pixel data and second color pixel data in a predetermined color space into a deformed HSV color space; a second transformation section that transforms the first color pixel data and the second color pixel data transformed into the deformed HSV color space into a three-dimensional x, y, z coordinate representation; and a color distance measurement section that measures a relative color distance between the first color pixel data and the second color pixel data on the basis of the first color pixel data and the second color pixel data transformed into the x, y, z coordinate representation. In the deformed HSV color space, maximum saturation is larger than maximum saturation in an HSV color space for a cone model at lightness between maximum lightness and minimum lightness, and the saturation is 0 at the minimum lightness.
