37.4: Accommodation Response in Viewing Integral Imaging

Visual discomfort has been the subject of considerable research in relation to stereoscopic and autostereoscopic displays. In this paper, the measurement of accommodation response in viewing integral imaging has been performed. Integral imaging is the three‐dimensional display technology proposed by Lippmann which shows full parallax images and does not need any additional equipment. Recently the integral imaging system was rapidly improved thanks to the progress of flat panel displays such as liquid crystal display, however so far, no definitive answer has been given to the visual fatigue related with viewing integral imaging system. The measurement results indicate that the accommodation response was in proportion to the perceived depth in integral imaging just as when the observer views real objects. The accommodation response is concluded not to be fixed on the display panel, but to follow similar response as if the physical objects exist on each depth.
