ABSTRACT:
An autostereoscopic system has a taking section for taking an image of a predetermined reference plane and outputting an image signal composed of a plurality of parallax images based on the taken image of the predetermined reference plane, and a playback section for reproducing a 3-D image based on the image signal output by the taking section. The taking section is composed of TV cameras, each having a convex lens and an image pickup screen, which are arranged in the horizontal direction, and the playback section is composed of image output screens arranged in the horizontal direction for outputting inverted parallax images of those at the image pickup screen, a large Fresnel convex lens disposed in front of the image output screens, and convex lenses, each being disposed between each of the image output screens and the large Fresnel convex lens, for projecting the inverted parallax images on or along the effective lens plane of the large Fresnel convex lens.
