Abstract
A plurality of preset palette data are stored in a ROM. User palette data are input through an RS232C interface and stored in a nonvolatile RAM. Based on an instruction from a user and other information such as a signal indicating the status of an illumination switch, a MPU selects one of the palette data and sets the selected palette data in a look-up table. Image data representing a map, present position, etc. is converted into color data by the look-up table, and then to an analog video signal for a color CRT. A display can be made using the palette data prepared by the user.
