ABSTRACT:
A color conversion device for color-converting an input image signal in an input color reproduction region of a source device, in a predetermined color space, by mapping the input image signal into an output color reproduction region of a destination device in the predetermined color space, comprising: a calculation portion for calculating a mapping destination in the output color reproduction region of a pre-specified characteristic point in the input color reproduction region; a correction portion for correcting the output color reproduction region such that a region including a saturation higher than the calculated mapping destination is eliminated; and a mapping portion for mapping the input image signal into the corrected output color reproduction region, is provided.
