PROBLEM TO BE SOLVED: To expand latitude in a color of an image. SOLUTION: A rendering engine 21 block transfers the data to be color converted from a display buffer 12 when the plotting of the data by one frame for the display buffer 12 is ended, and imparts them to a CLUT storage part 5 storing CLUT as an index, and block transfers again the color converted data obtained thus to the display buffer 12 to make store them. In a CRT controller 14, the color converted data are read out from the display buffer 12 through the rendering engine 21, and are supplied to a CRT 16 through a D/A conversion part 15 to be displayed. |
