摘要：A color conversion device includes a receiving unit receiving colorimetric values
obtained by measuring plural target-color images of different tones from pluraldirections; a memory storing a color conversion model associating a combination ofcolorimetric direction and color material amounts of respective colors and actuallymeasured color values; and a converter converting the colorimetric values into colorvalues including values indicative of amounts of glittering color material and other colormaterials, wherein the converter calculates, for each target-color image, a weightedaverage of color differences between colorimetric values of the target-color image incolorimetric directions and color values in the colorimetric directions obtained from themodel by using preset weighting coefficients and selects a combination of weightingcoefficients that makes tone characteristics closest to tone characteristics of the target-color images by changing the weighting coefficients when a combination of color materialamounts minimizing the weighted average is determined.
