A vector graphics data management unit 24 has a management table 25 holding pointers and priority ranks of caches to a cache unit 23. The management table 25 also holds a pointer whose priority rank is lower than those of pointers pointing to data cached by the cache unit 23. When receiving a drawing command, the vector graphics data management unit 24 carries out determination of whether a pointer included in the drawing command exists in the management table 25 and management of the management table 25 on the basis of a predetermined insertion rank when the pointer does not exist in the management table. |
