Abstract
A plurality sets of tristimulus values are calculated from input spectral data using a plurality sets of color matching functions. Correction coefficients for tristimulus values are calculated based on derivation methods of the plurality sets of color matching functions. Corrected tristimulus values are calculated from the plurality sets of tristimulus values using the correction coefficients.
