Integral three-dimensional television using a 2000-scanning-line video system.
We have developed an integral three-dimensional (3-D) television that uses a 2000-scanning-line video system that can shoot and display 3-D color moving images in real time. We had previously developed an integral 3-D television that used a high-definition television system. The new system uses -6 times as many elemental images [160 (horizontal) x 118 (vertical) elemental images] arranged at -1.5 times the density to improve further the picture quality of the reconstructed image. Through comparison an image near the lens array can be reconstructed at -1.9 times the spatial frequency, and the viewing angle is -1.5 times as wide.
