Patent ID: 8260045

Claim:
A color correction coefficient generator comprising: a first color value acquiring unit that acquires correction-intended color values in a color space configured of a plurality of color components including a particular color component; a second color value acquiring unit that acquires correction color values being color values in the color space configured of a plurality 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, wherein the generating unit generates a one-dimensional color correction table indicating associations between a plurality of density values of the particular color component and a plurality of color correction coefficients for correcting the respective density values, and the generating unit generates the color correction coefficient for correcting the particular density value of the particular color component, by performing local regression with weights assigned to weight coefficients for the correction-intended color values each having the particular color component at a density of a different density value, each of the weights determined according to a difference between the particular density value and the different density value.
