Abstract
Determination is made whether or not memory contents have been changed for each memory block. A physical memory corresponding to the memory block whose contents have not been changed is released as an area where no rendering data is stored. Then such area is managed distinguishably from other areas where rendering data are stored. As a result, memory areas are effectively utilized.
