Abstract

An image converter (35) converts an image rendered at a given vertical synchronous frequency into an image compatible with the specification of a display (60). A frame memory (47) holds the image converted by the image converter (35) by switching a plurality of buffers. A display (60) controller (50) selects one of the buffers in accordance with the vertical synchronous frequency of the display (60), and scans out the image from the frame memory (47) accordingly. A switch instruction issuing unit (14) issues a frame buffer switch instruction for designating a frame buffer to scan out from subsequently, in synchronization with the vertical synchronous frequency of the display (60), instead of immediately after the execution of an image converting process by the image converter (35).
