PROBLEM TO BE SOLVED: To obtain a three-dimensional picture processor which quickly performs the rendering processing of high picture quality like the alpha blending or anti-aliasing with a light load. SOLUTION: Apex coordinates 112 outputted from a polygon cache 104 and picture coordinates 119 outputted from a display controller 107 are given to an internally divided value generator 105, and this generator 105 outputs an internally divided value 113 to a renderer 106. The renderer 106 generates a color data value of each sub-pixel and a blending mode 125 of each sub-pixel from the internally divided value 113 and a rendering parameter 114 and outputs them to a synthesizer 123. The synthesizer 123 receives color data values of sub-pixels, the number of which is the division number of a pixel, from the renderer 106 as the input and synthesizes them to output a synthesized color data value 121. |
