ABSTRACT:
A color conversion device that color-converts colors of input image data into colors used in a display unit for displaying images using at least white includes: a ratio calculating unit that calculates a lightness ratio and a saturation ratio between a color reproduction range in the standard color space and a color reproduction range in colors used by the display unit in L*a*b* space at least when a color outside of the color reproduction range in colors used by the display unit is calculated; and a color compressing unit that performs color compression on the image data based on the ratios calculated by the ratio calculating unit.
