ABSTRACT:
In this optical image projection system, a composite image is produced by the superimposition of images from a plurality of separate optical projectors. Each optical projector includes a lamp, a transparency, colored light filters and a projection lens. One projector projects an image directly onto the screen. The other optical projectors include mirrors adjustable to superimpose their images with the directly projected image to form a composite image. The intensity of the lamps may be modulated by a color organ driven by an audio signal source to produce color images which change in intensity and hue reflecting the spectral content of the audio source. The composite image may also be changed with time by using liquid crystal display matrixes modulated by applied video signals.
