Abstract
A color conversion device includes a region judging section for judging which region of a three-dimensional color space contains an input value, and/or a representative points-dispersed axis selecting section for selecting a representative points-dispersed axis which is nearest to said input value. Additionally, the color conversion device includes a representative points selecting section for selecting representative points in the vicinity of the input value among representative points discretely arranged along (or within) the selected representative points dispersed axis; a look-up table (LUT) which stores coordinates of representative points and color correction data; and a linear interpolation section for performing color conversion by weighting based on the selected representative points.
