Research on 3DTV at NHK STRL

Three human factors, namely, visual naturalness, comfort/discomfort, and visual fatigue, play key roles during viewing of stereoscopic 3DTV. Current stereoscopic 3DTV systems mainly use vergence and binocular disparity as depth cues. Accordingly, the relations between these factors and shooting and display parameters were clarified. It was experimentally shown that discrepancy between vergence and accommodation causes visual fatigue. In addition, two spatial-imaging systems, namely, an integral 3DTV system and holographic 3DTV have been developed as prototypes. The Integral 3DTV system is based on integral photography. With this system, the processes from shooting to displaying 3D images are done in real-time. An experimental setup for spatial imaging was developed and used to display a 3D image without the need for 3D glasses.
