A display processor increases graphics display performance. The display processor includes: an OSD plane having a first OSD area and a second OSD area for storing graphics images; and a Z-order manager, which stores a vertical order assigned to the first OSD area and the second OSD area, and which provides a notification regarding that vertical order. This display processor also includes a CPU, which executes a downloaded application, thereby storing the graphics images in the first OSD area and the second OSD area based on the vertical order notified by the Z-order management unit; and a display which superimposes the graphics images stored in the first OSD area and the second OSD area in accordance with the abovementioned vertical order, and displays the images. |
