Environment-adapted image display system and image processing method

摘要

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 (Y 3 , x 3 , y 3 ) measured by a color light sensor 60 and converted by an Y 3 x 3 y 3 conversion section 143 is substituted into Y 1 , which is a Y value of an ideal environment, by a Y substitution section 142 ; color difference between the substituted color signals (Y 1 , x 3 , y 3 ) and ideal color signals (Y 1 , x 1 , y 1 ) is obtained by a color difference calculation section 145 ; and an environment subjective coefficient correction section 148 corrects the color difference when the color difference does not lie within a permissible correction range, and use the corrected color difference (Deltax', Deltay') to correct the image display information.
