Abstract
Official abstract text for this publication.
A color conversion coefficient generating apparatus includes a color vision degree coefficient calculating unit and a color conversion coefficient calculating unit. The color vision degree coefficient calculating unit calculates a color vision degree coefficient indicating the degree of color vision deficiency. The color conversion coefficient calculating unit calculates a color conversion coefficient used to convert an input color value, on the basis of correspondence between the color vision degree coefficient, calculated by the color vision degree coefficient calculating unit, and sensitivity characteristics of long- (L), medium- (M), and short- (S) wavelength-sensitive cones.
