ABSTRACT:
Special effect television picture transitions in which the new picture grows from a point on the television screen to occupy the entire screen, displacing the old picture, can be made to originate at any point of the television screen and to bring the picture to occupy precisely the entire television screen under control of a single actuating lever moved to produce the entire transition. The special effect picture size voltages which conventionally control the size of the special effect picture are inverted and multiplied by the corresponding picture shift voltages (horizontal and vertical) to produced inputs to the conventional function generators controlling the position of the special effects picture.
