Patent ID: 7817153

Claim:
A rendering apparatus comprising: a rasterizer which generates pixels corresponding to graphics to be rendered, the pixels being obtained by dividing a graphic rendering area in a matrix, the graphic rendering area including a plurality of pixel groups each including N pixels arranged in a matrix (where N is greater than or equal to 8); pixel processing units each of which executes rendering operations for each of the N pixels in each one of the pixel groups, the pixels rendered by the same pixel processing unit being positioned substantially equidistantly and isotropically within the rendering area wherein the three pixels in vicinity to each other rendered by the same pixel processing unit form a first triangle when N=2 2n+2 (where n is a natural number, not less than 1) and form a second triangle when N=2 2n+1 within the graphic rendering area, the length of the shortest side of the first triangle is greater than N 1/2 , the length of the shortest side of the second triangle is N 1/2 , and the average length of the three sides of the second triangle is smaller than (N 1/2 (2+2 1/2 )/3); and memories which are provided in association with the respective pixel processing units and store data of the pixels rendered by the associated pixel processing units.
