Abstract
A circuit which expands monochrome character image patterns to color form for use in a raster scanned computer display system. Monochrome patterns are expanded from one bit per pixel to n bits per pixel. Foreground and background colors are programmable in a pattern generator which uses data from the expanded source patterns to select appropriate colors and characters for a destination pattern to be displayed. The expanded multicolor image is generated by hardware.
