Abstract
A video processing system in which the shape or size of an image can be altered by providing a map of address signals representing the addressess in the store to which input video signals must be written to produce the desired change. These addresses can be manipulated so that there are a number of changes to the image. Where there is an expansion in the image the address signals are filtered to prevent picture break up. The incoming video signals are written into the filtered addresses and then new picture points are interpolated to produce the desired expansion.
