ABSTRACT:
An image processing apparatus, able to improve the pixel fill rate and able to prevent an increase of memory resources and increase of memory access, provided with a color calculation circuit for performing pixel level processing based on supplied first attribute parameters of the Z and color (R, G, B) data and outputting second attribute parameters and (x, y) coordinate data supplied by a DDA circuit together with the results and a sub primitive generation circuit for expanding a plurality of stamps to a plurality of sub primitives (sub stamps) based on the second attribute parameters of the color calculation circuit, generating expanded coordinates corresponding to the expanded sub stamps based on the (x, y) coordinate data of the DDA circuit, and outputting the same as the drawing parameters after expansion and the expanded graphics drawing coordinates to a memory controller, and a method of the same.
