Abstract

PURPOSE:To simplify control by connecting plural pieces of color pallets in parallel, using a multiplexer to select and switch valid signals of the color signals outputted from the respective color pallets to display in respective window screens. CONSTITUTION:Image information written in a frame memory 2 is read out through a shift register 3, and inputted to the plural color pallets 4. This information from the frame memory 2 is converted to PGB color intensity signals by the color pallets 4. The output signals from these pallets 4 are inputted to a multiplexer 5. From among the signals thus inputted to the multiplexer 5, the valid PGB signals are selected by selection signals generated by a selecting circuit 6 that uses display timing signals for a cathode-ray tube screen, and displayed on the screen after A/D conversion. As a result, plural window pictures using different display colors can be displayed on the same screen.
