PROBLEM TO BE SOLVED: To properly scroll an image even when a low-power CPU and a small-capacity memory are used.SOLUTION: A VRAM 14 has at least a space for one line of an image for storing data of the image to be displayed on a display part 16. A display control part 15 executes control to display the image indicated by the data stored in the VRAM 14 on the display part 16 on the basis of association information which associates an address on the VRAM 14 with a position on a display screen of the display part 16. Specifically, the display control part 15 concatenates an address of a pixel to be scanned last in the mth line and an address of a pixel to be scanned first in the m+1th line in the VRAM 14, sequentially reads data of the pixels in the order of raster scanning on the basis of the association information changed by a CPU 11, and sequentially displays the pixels in corresponding positions on the display part 16, to display the image on the display part 16. |
