Abstract
When a user pushes a scroll-direction key, an ECU obtains, from a memory, a division map corresponding to a division located in a direction designated by the scroll-direction key. The ECU then outputs the division map to a display controller. The display controller compresses the division map to store in a VRAM. At scrolling a displayed image, the display controller expands the compressed division map. It then outputs, to an image signal generator, only a necessary portion of the expanded division map. Thereby, the displayed image can be scrolled at high speed and easily recognizable for the user.
