ABSTRACT:
A stereoscopic display which enables plural persons to simultaneously observe stereoscopic images includes a color liquid crystal plate for displaying stereo-pairs composed of left and right eye perspectives in time-interlaced manner, a monochrome TV display disposed behind the color liquid crystal plate for displaying binary and inverted binary images of half face of each observer so as to be synchronized with the time-interlaced display of the color liquid crystal plate, and a large convex lens disposed between the color liquid crystal plate and the monochrome TV display so as to focus the observers' optical images on the screen of the monochrome TV display in geometrical agreement with the observers' face images displayed thereby. And an infrared TV camera is disposed so as to take observers' images by way of the large convex lens and input observers' face images to the monochrome TV display.
