Patent ID: 7480083

Claim:
A color processing apparatus for calculating a color signal indicated by a plurality of color components from spectral data of an input color, said apparatus comprising: a holding unit constructed to hold information for calculating spectral data with respect to each category of a plurality of categories of objects; an input unit constructed to input spectral data; a generating unit constructed to generate information for calculating spectral data, based on the spectral data input by said input unit; a deciding unit constructed to decide, based on the information for calculating spectral data generated by said generating unit and the information for calculating spectral data held by said holding unit, a category corresponding to the spectral data input by said input unit from the categories held by said holding unit; a calculation unit constructed to calculate, from the spectral data input by said input unit, a color signal indicated by a plurality of color components; a storing unit constructed to store the category and the color signal.
