Evaluation of Perceptual Resolution and Crosstalk in Stereoscopic Displays

Abstract

Perceptual resolution and crosstalk of active and passive stereoscopic 3D displays are evaluated by subjective tests. Test patterns of gratings with various contrast and spatial frequencies are used to determine the contrast thresholds, from which the contrast sensitivity of human visual systems is obtained. Perceptual resolution tests show that viewers can perceive the highest vertical frequency on active displays, but not on passive displays. However, the contrast sensitivity is higher for passive displays than active displays for all other frequencies. Viewers can perceive frequency components with lower contrast, except for the highest frequency, more easily on passive displays than on active displays. Perceptual crosstalk tests show that interocular crosstalk is a function of spatial frequency. Crosstalk is lower on passive displays than on active displays.
