ABSTRACT:
A processing circuit which is arranged to operate in three modes. The first mode is to act as a brush processor in video graphics creation combining incoming video signals with stored video signals to produce a graphic signal. The second mode allows an image to be composed from two or more input pictures using stencil signals. The third mode is useful in still picture applications where one frame is to be viewed and the next previewed. Stencil signals allow the operator to cut or fade from one frame to the other.
