Abstract
A raster-scan display system for computer-generated images in which each raster line is quantized into a number (N) of sets of image elements each successive set being displaced in time, with respect to the line start, by 1/N of the duration of one element. The corresponding video signals are summed for each line and the resultant signal is displayed. The technique provides a visual image with graded intensity changes more nearly simulating a television type image, instead of a stepwise changing image. In one form of the invention, a triangular hold technique is used, that is, the display is delayed to permit of a linearly changing intensity charge between consecutive elements of different intensity.
