Psychophysical evaluations of a current multi‐view 3‐D display: Its advantages in glossiness reproduction

Abstract— Although two‐view 3‐D displays requiring stereo glasses are on the market, the shape of objects they present is distorted when the observer's head moves. This problem can be solved by using a (passive) multi‐view 3‐D display because such a display can produce motion parallax. Another problem has to do with the surface quality of the presented object, but little is known about the fidelity of such displays as far as the surface quality goes. Previously, it was found that a two‐view 3‐D display has a problem in which glossiness deteriorates when the observer's head moves and that it can be alleviated by using a head tracker, whose data enables the display to produce correct motion parallax and luminance changes when the viewer's head moves. Here, it was determined whether this problem can be solved by using commercially available multi‐view 3‐D displays, whose finite number of viewpoints and certain amount of cross‐talk, however, make luminance changes inexact and smaller than they should be. It was found that this display can solve the problem to a certain extent.
