Abstract: The disclosure is of a system for steering a landing light pattern by storing data to increase the illumination intensity for each picture element by a selected amount along a scanline in a memory circuit (11) and, then, addressing the memory circuit to begin its readout at predetermined starting points. A skewing or warping of the light pattern is obtained by applying a displacement factor to the beginning point for each successive scanline, so that each scanline is read out beginning at a progressively different point to cause the shape of the landing light pattern to be varied in a predetermined manner.
