PURPOSE: To improve an availability factor of memory of a conversion table by registering plural color data instead of overlapped transparent code in the conversion table. CONSTITUTION: A video display processor(VDP) 14 which controls display under the control of CPU 11 generates color data (RGB data) displayed on a screen in a color resolution specified by CPU 11 based on the various image data stored in SRAM(Static RAM) 15 and DP-RAM(Dual Port RAM) 16. Here, instead of a transparent code TC duplicately stored in a conversion table, by allotting plural color data at the head of each color data group and also making the color data readable according to a modification code, while color data can be read also in a normal color code, a full color display in a number of colors corresponding to a color look-up table capacity is enabled also in displaying in multi-color corresponding to the color data group.
