US Patent:

41836332, Jan 15, 1980

Filed:

Jan 31, 1977

Appl. No.:

5/764404

Inventors:

Arthur P. Kent - New York NY
Mortimer Marks - New York NY

Assignee:

Marks Polarized Corporation - Whitestone NY

International Classification:

G03B 3508

US Classification:

352 60

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.

US Classification:

352129

Abstract:

Stereo pairs suitable for motion picture projection are derived from conventionally taken motion picture film by selection of frames and rearrangement thereof in side by side relationship upon a continuous strip of motion picture film. The pairs so prepared may be incorporated into film containing conventionally photographed stereo frames to provide a compatible system for 3-dimensional motion picture projection.
