Abstract:
1. A spectral characteristic correction apparatus which corrects a spectral characteristic characterizing a color signal including a plurality of chrominance signals, the apparatus comprising: a correction coefficient calculating unit for calculating, based on basic color signals obtained by photographing a color chart including a plurality of color patches using a first image pickup device and reference color signals stored in advance which correspond to the basic color signals, a correction coefficient for performing correction for approximating one of the basic color signals and the reference color signals to the other of the basic color signals and the reference color signals; a spectral characteristic correcting unit for correcting a spectral characteristic of interest to be corrected by using the correction coefficient calculated by the correction coefficient calculating unit; and a conversion coefficient calculating unit for calculating, based on the spectral characteristic of interest corrected by the spectral characteristic correcting unit and a target spectral characteristic of a second image pickup device which represents a targeted color reproduction, a conversion coefficient for performing conversion for approximating the corrected spectral characteristic of interest to the target spectral characteristic.
