COLOR IMAGE DISPLAY METHOD

摘要

PURPOSE:To execute image effect such as fade-in/out, cross fade and glow for plural images without increasing bitmap capacity and display circuit scale. CONSTITUTION:A color lookup table (CLUT X) 221 is synthesized from a 201 and a 211 with arithmetic process. A bitmap X 222 is similarly synthesized from a 202 and a 212 with arithmetic process. A synthetic image is displayed by using the CLUT X 221 and the bitmap X 222. Image effect switching in displayed synthetic image with high quality is executed by changing color data in the 221 synthesized by arithmetic process with a time function.
