ABSTRACT:
Light (22) is projected from an image projector (20), in response to an image information signal (18) and is controllably refracted in response to a first control signal (26), for projecting refracted light (27) onto a screen (28). The screened light is for providing viewable images of varying size occupying all or part of the screen. The viewable images are refracted in response to a second control signal (64) for viewing the images of increasingly smaller size with correspondingly increasing magnification.
