The present invention intends to provide an image processing apparatus that can process geometrical primitives rapidly and with restrained memory consumption. A sequence of vertex data of a primitive sequence is stored in an index buffer, and size data of the primitive is stored in the head of the sequence. The result of processing of the primitive sequence in a geometry shader is stored in a cache buffer, and a primitive output, which is the output result stored in the cache buffer, is reused in reprocessing of the primitive processed in the geometry shader.
