Color conversion coefficient generating apparatus and method, color processing apparatus, and non-transitory computer readable medium |
摘要 |
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. |

1. A color conversion coefficient generating apparatus comprising:
a color vision degree coefficient calculating unit configured to calculate a color vision degree coefficient indicating a degree of color vision deficiency; and a color conversion coefficient calculating unit configured to calculate a color conversion coefficient used to convert an input color value, on the basis of correspondence between the color vision degree coefficient and sensitivity characteristics of long- (L), medium- (M), and short- (S) wavelength-sensitive cones, wherein the degree of color vision deficiency indicates a severe color vision or weak color vision, and in the case of weak color vision, the degree thereof. |
