ABSTRACT:
The address calculating unit calculates a virtual address of a page for each pixel of a rectangular region of a predetermined size that is included in a screen. The acquiring unit acquires a physical address in correspondence with the virtual address of each pixel of the image information for which writing is requested, in accordance with a conversion table. The writing unit writes the image information for which writing is requested at the acquired physical address. The detecting unit detects an updated portion of the image information the content of which does not match before and after the writing, in units of pages. The compressing unit compresses the image information of the updated portion that is detected.
