ABSTRACT:
A three-dimensional photographing and three-dimensional playback device by spatial time-sharing method has a taking section having a convex lens, an image pickup screen spaced from the convex lens at a distance equal to the focal length of the convex lens, and a pin hole movable on a surface of the convex lens, and a playback section having a cylindrical lens, an image output screen spaced from the cylindrical lens at a distance equal to the focal length of the cylindrical lens, and a vertical slit movable on a surface of the cylindrical lens. The pin hole in the taking section and the vertical slit in the playback section are scanned in synchronization whereby any image can be photographed and played back three-dimensionally without using any special instrument such as polarized glasses, etc.
