To provide an image generating system, program, and information storage medium for expressing various conversion processing with a small processing load.
The pixel data (color, α value, Z value, luminance or the like) of an original image are set in an indirect texture storage part 177, and data for conversion are set in a normal texture storage part 178. The pixel data of the original image read from the indirect texture storage part 177 are set to texture coordinates, the data for conversion are read from the normal texture storage part 178, and the read data for conversion are plotted in pixels to be plotted so that the pixel data of the original image can be converted. A first α value obtained by converting the Z value of the original image is combined with an α value for α non-uniformity setting so that a second α value can be generated, and the color of each pixel of the original image is combined with a fog color on the basis of the second α value. The Z value or luminance are converted into the α value, and a depth-of-field image or a halation image are generated on the basis of the acquired α value.
