COLOR CONVERSION APPARATUS, IMAGE FORMING APPARATUS, COLOR CONVERSION METHOD, AND COLOR CONVERSION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a color conversion apparatus that performs color conversion with high accuracy while reducing the amount of computation.SOLUTION: An image forming apparatus 1 is a color conversion apparatus that converts an acquired first color value 401 into a second color value 402. A color position calculation unit 120 calculates the hue surface and chroma of the first color value 401. A color value conversion unit 130 converts the first color value 401 into the second color value 402 with a K-monochrome color conversion table 310 in which achromatic colors are set as monochromatic colors when the chroma of the first color value 401 calculated by the color position calculation unit 120 is larger than a predetermined threshold, and with a hue surface color conversion table 320 in which achromatic colors are set as a mixed color of a plurality of colors when the chroma is equal to or smaller than the predetermined threshold.
