PURPOSE:To consecutively display map images by providing a storage device having plural screen frames and a display image controller between an arithmetic device and a display device. CONSTITUTION:Map data from the storage device 1 is image-converted by the arithmetic device and is inputted to the screen frame 6 of a frame storage device 4. The frame 6 is bigger than the screen 7 of the display device 3 and have plural screens. Therefore, the display starting position of the screen 7 can be set and designated to any positions of the frame 6 by sending a signal from an input device 8 to a display controller. Thus, the joint of the map images displayed on the display device 3 can be eliminated and the map images can consecutively be displayed. |
