ABSTRACT:
Apparatus for processing a video signal representing distribution of optically-perceptible information over a video raster includes a video combiner for receiving an input video signal and a delayed video signal and combining the input video signal and the delayed video signal to provide an output video signal. A memory receives and temporarily stores the output video signal and provides the delayed video signal, and read/write circuits access the memory so that pixels of the output video signal are spatially translated relative to the video raster when the output video signal is written into and read from the memory.
