PROBLEM TO BE SOLVED: To provide an image generating system, program, and information storage medium for expressing various conversion processing with a small processing load. SOLUTION: The pixel data (color,αvalue, 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 firstαvalue obtained by converting the Z value of the original image is combined with anαvalue forαnon-uniformity setting so that a secondαvalue can be generated, and the color of each pixel of the original image is combined with a fog color on the basis of the secondαvalue. The Z value or luminance are converted into theαvalue, and a depth-of-field image or a halation image are generated on the basis of the acquiredαvalue. COPYRIGHT: (C)2005,JPO&NCIPI
