Abstract
Hue, lightness, and saturation signals are obtained from an input signal, and hue direction intensity signals with respect to respective unit colors are determined using color corrective intensity functions for respective hues which have been established based on measured values. These hue direction intensity signals are multiplied into corrected intensity signals with respect to the respective colors, which are multiplied by desired correction coefficients. Resulting product signals for the respective unit colors are added into corrected signals with respect to given color signals.
