Abstract
A video signal processing system which produces the same output image as the input image but with a size and/or shape change applied to it. The incoming video signals are written into the frame store in sequence but read out in an order determined by the output image required. When compressions in the image occurs the luminance signals are filtered prior to writing in the store.
