Color conversion treatment manner, adaptation color gamut of the color space

摘要

PPROBLEM TO BE SOLVED: To provide a color conversion processing method and a color conversion processor for reducing the turbidity of a high saturation region or the distortion of gradation to be generated at the time of compressing a color region by a color printer or the like, and to provide a recording medium. PSOLUTION: This method comprises a step for calculating the maximum saturation point Pcmax and Qcmax, a step for calculating a point Po from a color P to be converted and an anchor point Pa, a step for mapping the point Po to a point Qo, and a step for converting the color P to be converted to a point Q based on a rule to map a point on a segment connecting the anchor point Pa to the point Po to a point on a segment connecting an anchor point Qa to the point Qo.
