摘要：
A color conversion coefficient calculation apparatus includes: a conversion coefficient calculation section that calculates, as a color conversion coefficient for converting a first color signal made up of a plurality of chrominance signals into a second color signal made up of a plurality of chrominance signals, a color conversion coefficient for converting a first spectral characteristic which characterizes the first color signal in a standard fashion into a second spectral characteristic which characterizes the second color signal; a correction coefficient calculation section that calculates a correction coefficient for approximating a base color signal which is the first color signal corresponding to a plurality of base colors into a reference color signal obtained based on the first spectral characteristic corresponding to a plurality of base colors; and a conversion coefficient correction section that corrects the color conversion coefficient by using the correction coefficient.
