ABSTRACT:
A three-dimensional image special effect apparatus wherein the motion of an image across a display screen is controlled by a track ball and rotary ring. The amount of movement is controlled and scaled according to the theoretical depth of the special image on the screen such that the greater the depth of the special image, the less it is moved by a given rotational amount of the track ball or rotary ring.
