Abstract
An image projection system and method of use at a venue, e.g., a sports or entertainment arena, having an area or field into which an image is to be projected by the system. The system includes laser devices and associated components, e.g., a computer-based controller, for generating and projecting the image into the field. The projection system additionally comprises an override subsystem, e.g., infrared transmitters and associated detectors, forming an enclosure surrounding the field for determining if a living being has entered the field and for providing an electrical signal indicative thereof. This signal may be used automatically or manually for effecting the termination of the display.
