Paper Abstract

The integral method is one of the ideal means for forming 3D spatial images like real objects. It requires, however, extremely high-resolution device in order to satisfy sufficient resolution and wide viewing angle. The authors have been examining integral 3D television systems applying the Super Hi-Vision (SHV) system, which uses ultrahigh-definition LCOS, D-ILA devices. This paper describes the experimental integral 3D display and approaches to improve the quality of elemental images, which are projected behind the lens array, by decreasing blurs and improving registration accuracy. The display panels are four chips of D-ILA (4096 × 2160 pixels), each of which is used for R, B, G1 and G2 (pixel-offset method). The optics of the R/B projector and the G1/G2 projector are accurately aligned by a half mirror and the elemental images are formed on a 22 inches screen. The diffuser of the screen is a thin LC film with sufficient resolution and homogeneous visual field. The lens array consists of newly developed short focus lenses to enable wide viewing angle for multiple viewing. A drastic improvement of the 3D image quality has been achieved together with the electronic distortion correction technique.
