Summary:PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of quickly determining the inside and the outside of a stamp. SOLUTION: An image processing apparatus 45 has a DDA setup part 1, a context part 2, a linear equation calculation part 3, an XY calculation part 4, an edge determination part 5, a DA control part 6, and a mask generation part 7. A stamp is processed while alternately switching a plurality of threads, and a stamp to be next processed is instantaneously switched when it is determined that the stamp is on the outside of a polygon, so that unnecessary processing of the stamp being on the outside of the polygon is eliminated to perform efficient rasterization processing.
