ABSTRACT:
Stereo pairs which have been printed on a single film strip are directed and focused upon a screen by an attachment for a standard motion picture projector. The images are overlapped and polarized at right angles to the other upon the screen by an optical device having abutting elements. The stereo pairs on the film are separated by an opaque band to define the edges of the projected image and mask element abutment. Indicia marks may be provided on the film to enable the positioning of the right and left images on the film in the gate to avoid pseudo stereo projection. A film format for stereo pairs uses a dark bar centered at the aperture on the film or gate.
