This invention employs an incremental technique for performing a perspective transformation on a planar television image. The equipment modifies the coefficients to a two by two matrix multiplier at the pixel or line rate. This allows for perspective generation along either the X or Y axis of the television screen. The invention will also provide perspective generation for rotation of the image about the Z axis in addition to the rotation about one of the X or Y axes.
