20.4: Objective Evaluation of Multi‐View Autostereoscopic 3D Displays

Abstract

AbstractAutostereoscopic 3D display technologies offer attractive solutions for the entertainment and media consumption. These technologies make it possible for the users to obtain more immersive experience by adding the real depth to the visual content shown on the display. The method used for the creation of the sensation of depth or stereo illusion as such contains several issues that need to be carefully considered so that sufficient image quality is maintained. Traditionally methods used for the 3D image quality evaluations have had their base in subjective testing. We believe that optical measurements can be used as an efficient tool for the 3D display characterization. We have developed objective characterization methods for the autostereoscopic displays and investigated how parameters affecting the stereo image quality can be defined, measured, and the effect on the stereo image quality evaluated. In this paper previously presented methodology is extended to cover autostereoscopic multi‐view displays, where a distinction between displays with continuous and discontinuous motion parallax is made. We are focusing on the definition for the 3D luminance and luminance uniformity, that are equally important, as well as 3D crosstalk, which we think is the dominant factor in the evaluations of the perceived 3D image quality.
