ABSTRACT:
The flicker which results when an ordered dither image is displayed in an interlaced-field format is eliminated by energizing each display point of the interlaced-field display to have an intensity proportional to the average intensity of a cluster of (illustratively four) cells of the dithered image rather than the intensity of a single one of the cells.
