Abstract:
The color correction coefficient generator includes: a first color value acquiring unit that acquires correction-intended color values in a first color space configured of color components including a particular color component; a second color value acquiring unit that acquires correction color values being color values in a second color space configured of color components including the particular color component, and the correction color values being color values used to correct the correction-intended color values; a weight coefficient acquiring unit that acquires weight coefficients for the correction-intended color values; and a generating unit that generates a color correction coefficient on the basis of the correction color values for correcting the correction-intended color values having the particular color component at a density of a particular density value and on the basis of the weight coefficients for the correction-intended color values, the color correction coefficient used to correct the particular density value.
