PROBLEM TO BE SOLVED: To provide a synthesizing system (300) including an optimized alpha channel synthetic module (303). SOLUTION: A synthesizing system (300) optimizes range correction in an alpha channel synthetic module (303) by using a constant divider and delaying correction of alpha values until the alpha values in all contributing areas are added. An uncorrected value of opacity is used for indexing to a reference table to shorten a data processing path to a multiplier regarding a processing after prior multiplication of color values from all the contributing areas. |
