Abstract
The present invention provides improved burnout imprinting prevention by slowly moving the position of screen content to ensure that no one area of the guns is unused for a long period of time. Optical and/or mechanical elements are provided to redirect the projected image to the center of the screen. As the image moves on the projection guns the optical elements are positioned accordingly to shift the projected image such that the viewable image is fixed.
