Abstract
PURPOSE:To enable to arbitrarily change the hue of screen, by the code conversion for the output from display RAM. CONSTITUTION:The data written in the display RAM6 is read out every 1 byte and fed to the parallel-serial conversion circuit 7. Three sets of parallel latch circuits of the parallel-serial conversion circuit 7 latch the data from the display RAM6 and sequentially deliver the data with the signal A from the timing module 8 and convert them into serial signals. This output signal is inputted to the color conversion PROM, where it is converted into three color video signals C with the color code signal B from the CPU decode section 4. The three color video signal C and the synchronizing signal D from the synchronism circuit 9 are inputted to the Braun tube CRT to display the color picture on the disply screen.
