Abstract
Abstract A stereoscopic picture system which has a stereoscopic camera for picking-up a stereo-pair of images, a stereoscopic recorder, a stereoscopic encoder to selectively color each image of the stereo-pair and to superimpose them, a stereoscopic transmitter, a stereoscopic color display and a stereoscopic color viewing device. Each image of the stereo-pair in a color film system is selectively colored, or each is electronically colored in a color video system, to insure that the images are channeled separately through the color system to appear as two differently colored images at the display. Chromatic viewing devices, such as colored anaglyph glasses, are used by each viewer to channel one image to each respective eye. The viewer normally perceives a substantially black-and-white stereoscopic picture; however, a system for picking-up, recording, transmitting, reproducing, and viewing a full color picture is also described. The system relates to television, but has applications to graphic and visual displays and to film and motion pictures.
