Abstract
In this paper a procedure for crosstalk (CT) measurements on spatial-multiplexed multi-user autostereoscopic 3D displays with so-called viewing distance control (VDC) is presented. VDC makes use of a rendering method which allows shifting of the viewing distance for multiview displays by using a novel distribution of the content at sub-pixel level. Methods for CT measurements to date cannot be used as the measurements have to be executed at distances that are not defined in the standard procedures for stereoscopic displays. The measuring procedures used so far are not applicable, as neither a measurement process nor any test images are defined for the use at different viewing distances. As separate CT-measurement specifications for two-view and multiview autostereoscopic displays already exist, the authors propose a unified measurement process. This process is supposed to utilize both, the equipment, as well as the physical arrangement of measuring subject and instrument that are used so far. It has to be considered that, due to the basic functional principles, several quality measurement and evaluation criteria for 3D displays have emerged. Different autostereoscopic display technologies lead to different measurement procedures. A unified method for analyzing image quality features in 3D displays, requiring no enhanced effort but offering comparable results, is desirable.
