Disclosed is a graphics processing apparatus capable of drawing graphics at high speed with a small memory capacity even in the case of drawing graphics in which a drawing element and a clip element exist mixedly or which has many overlaps. A drawing command is interpreted by a command interpretation unit and data is converted to linear vectors by a vector data generation unit. A display list generation unit generates a display list. With respect to graphics in which a clip element and a drawing element exist mixedly, display lists of both elements are merged and a clipping process is performed at the level of the display lists while executing predetermined determination. In the case of graphics having many overlaps, the overlaps are similarly removed at the level of the display lists. A display list drawing unit has a processing unit of 2N and performs drawing while executing a DDA operation in parallel. When the number of straight lines exceeds 2N, the process is divided so that the number is equal to or smaller than 2N.
