ABSTRACT:
A circuit for converting a monochrome video signal into individual video color signals includes a gate means for individually energizing the color guns of a color picture tube. Control logic sequentially enables the gates so that only one electron gun is energized at a given instant. The circuit works in cooperation with a commercially available pattern generator so that a plurality of rows of patterns of a particular color are scanned across the face of the screen. Because of the sequential scanning, various rows of the selected pattern are composed of the three primary colors.
