1. A color processing apparatus comprising: a setting section, constructed to set personal color matching functions obtained by a color matching experiment and to set standard color matching functions; an inputting section, constructed to input spectral image data; a first calculator, constructed to calculate color values by applying the personal color matching functions to spectral data corresponding to a pixel of the input spectral image data; a second calculator, constructed to calculate color values by applying the standard color matching functions to the spectral data; and a generator, constructed to generate corrected spectral image data by generating spectral data corresponding to a pixel of the corrected spectral image data based on a difference between a first calculation result of the first calculator and a second calculation result of the second calculator.
