ABSTRACT:
To provide an environment-compliant image display system, image processing method, and information storage medium that enable correction of images within a shorter time, a Y value of color signals (Y3, x3, y3) measured by a color light sensor60and converted by an Y3x3y3conversion section143is substituted into Y1, which is a Y value of an ideal environment, by a Y substitution section142; color difference between the substituted color signals (Y1, x3, y3) and ideal color signals (Y1, x1, y1) is obtained by a color difference calculation section145; and an environment subjective coefficient correction section148corrects the color difference when the color difference does not lie within a permissible correction range, and use the corrected color difference (Δx′, Δy′) to correct the image display information.
