Abstract

Recently, a stereoscopic technology called DFD (Depth-fused 3D) developed in NTT. With this method two images are overlapped, displaying two planes with different depths. Humans usually perceive such overlapped two images as one image with one depth. When Humans perceive the depth of the DFD image, it is assume that they use factors of depth perception, such as lens accommodation, convergence and binocular parallax. Researchers have studied depth perception factors during the viewing of DFD images. However, studies have not clarified the effects of viewing of DFD images on accommodation. In this study, we measured lens accommodation in subjects who gazed at DFD images. We verified that a viewer’s lens accommodation can adjust to DFD images.
