ABSTRACT:
A projection system for a theatre in the round having a plurality of moving image projectors. The projectors can be either film projectors or television-type projectors. They project in an essentially cylindrical surface which is viewed by people at a viewing location. A lens is associated with each moving image projector, the lens having an optical axis located at or above a top edge of the viewable portion of the cylindrical surface. A source of moving images is associated with each lens, the center of which source is located above the optical axis of the associated lens such that moving images are projected by each lens downwardly toward a portion of the essentially cylindrical surface in an essentially distortion-free manner.
