Abstract
A visual display system selectively operable to display, upon command, any one of a plurality of different bits of information. The exemplary embodiment is intended for use in an indoor golf game to display scenes representing perspective views of any one of a plurality of different locations on any one of a plurality of different holes on a golf course. The system also includes a ball spot projector for projecting a spot of light on the projected scene in a manner to simulate the trajectory of a golf ball in flight. The scene selection system is a digital servo system for economy and reliability and is operative to minimize film fading on frequently used scenes such as a scene depicting the view from the tee on a golf hole and is further operative to reduce fading of any particular scene due to prolonged exposure by automatically shifting to an advertising scene or the like when the scene selection has not been made after a predetermined time.
