PROBLEM TO BE SOLVED: To provide a program, an information storage medium and an image generation system for generating a display image by adding effects to an original image without damaging the texture of an original image. SOLUTION: An original image Pic(Org) and an effect image Pic(Eff) corresponding to the original image Pic(Org) are plotted for a visual field image where an object space is viewed from a point of view. The respective pixels of the effect image Pic(Eff) are plotted by color distribution with the given reference color as the center of distribution. As for the pixels brighter than the reference color in the effect image Pic(Eff), color information corresponding to a difference between the color of the pixel and the reference color is added to the color information of the corresponding pixel of the original image Pic(Org) according to anαvalue by additionαblending. As for the pixel darker than the reference color in the effect image Pic(Eff), the color information corresponding to the difference between the color of the pixel and the reference color is subtracted from the color information of the corresponding pixel of the original image Pic(Org) according to theαvalue by subtractionαblending.
