Abstract
Abstract A method and a system for producing stereoscopic 3-dimensional images from a single motion picture video film having a plurality of frames containing successive images which are produced from a single video camera in motion. The motion picture video film is produced by displacing the camera along an axis with a viewing axis of the camera oriented substantially perpendicular to the axis of displacement of the camera. Images of the motion picture video film are overlaid or alternated in a synchronized fashion and separated by a time sequence to produce video signals of composite images capable of producing 3-dimensional images which can be viewed on a screen with eyeglasses having lenses conditioned to view separate ones of the overlaid or alternating images, simultaneously, whereby a viewer person can observe a depth of field in the composite images. The video signals can be derived by using two film copies each feeding an associated one of two recording devices to produce time separated video signals which are multiplexed and then recorded in a further recording device to produce a video film of the composite images. The video signals may be produced by the use of a computer with composite image digital signals stored in the memory of the computer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
236 words
A system for producing stereoscopic 3-dimensional images from a single motion picture video film having a plurality of frames containing successive images which are produced from a single video camera in horizontal motion, said system comprising a computer having a recording medium, means for storing digital information signals on said recording medium, a display screen associated with said computer, a keyboard associated with said computer, program means to produce composite 3-dimensional digital information signals by generating said digital information signals representative of successive ones of said images superimposed or alternating in synchronism with time delayed digital information signals also representative of successive ones of said images, said composite 3-dimensional digital information signals displayed on said screen, a frame stabilizer circuit to monitor and adjust said digital information signals representative of said superimposed or alternating signals to correct horizontal and vertical alignment of said superimposed or alternating signals representative of images in said frames due to said horizontal motion, said program means permitting a user person by means of said keyboard to modify said time delayed digital information signals to vary the position of said superimposed images to modify a 3-dimensional image displayed on said display screen, and eyeglasses having having lenses conditioned to view separate ones of said overlaid or alternating images simultaneously whereby a viewer person can observe a depth of field in said images displayed and produced by said composite 3-dimensional digital information signals.
Claim 2
Independent Claim
