Reproducibility of crosstalk measurements on active glasses 3D LCD displays based on temporal characterization
Proceedings of SPIE Vol. 8288: Stereoscopic Displays and Applications XXIII
Crosstalk is one of the main display-related perceptual factors degrading image quality and causing visual dis-comfort on 3D-displays. It causes visual artifacts such as ghosting eects, blurring, and lack of color delitywhich are considerably annoying and can lead to diculties to fuse stereoscopic images. On stereoscopic LCDwith shutter-glasses, crosstalk is mainly due to dynamic temporal aspects: imprecise target luminance (highlydependent on the combination of left-view and right-view pixel color values in disparity regions) and synchro-nization issues between shutter-glasses and LCD. These dierent factors inuence largely the reproducibilityof crosstalk measurements across laboratories and need to be evaluated in several dierent locations involvingsimilar and diering conditions. In this paper we propose a fast and reproducible measurement procedure forcrosstalk based on high-frequency temporal measurements of both display and shutter responses. It permitsto fully characterize crosstalk for any right/left color combination and at any spatial position on the screen.Such a reliable objective crosstalk measurement method at several spatial positions is considered a mandatoryprerequisite for evaluating the perceptual inuence of crosstalk in further subjective studies.
