Three-Dimensional Motion Picture Applications

R. V. Bernier

Images on the retinae of the eyes, resulting when viewing real life subject matter, are not in themselves three-dimensional. The impulses from these images which travel to the brain supply the brain with the data it needs to build the three-dimensional vision which the observer sees in lieu of the subject itself. Present grainless motion picture color film is a nearly perfect medium of establishing synthetic images on the retinae which equal the natural ones. As a result, the data that reaches the brain is comparable to that which might emanate from natural images. The brain, detecting little difference, forms a synthetic vision nearly as perfect as natural vision. — The three-dimensional motion picture camera has been employed with success to capture all of the components of depth perception which are associated with natural vision. In addition high-speed and time-lapse applications have been developed which also incorporate factors of depth perception otherwise impossible to duplicate in natural vision. — A solution of the flicker problem in 16-mm, alternate-frame, stereo projection at 24 frames/sec has been provided through the use of the Morgana shuttle movement. Also the requirement for registration adjustments before or during projection has been eliminated by the use of a barrel-type polarizer which permits projecting through a single-lens axis.
