Abstract
A video processing system which can produce a different shape of output picture than the input. Addresses into which incoming picture points must be written to produce the desired shape changes are stored in a shape store. These addresses can also be manipulated in real time so that the position of the shape they define is changed. For example a Mercator projection of a map can be projected onto a globe and this globe could then be tilted, rotated etc.
