Abstract
Substantial progress in liquid-crystal
display and
polarization
film technology has enabled several types of
stereoscopic displays. Despite all progress, some image
distortions still exist in these 3-D displays, of which
interocular crosstalk—light leakage of the
image for one eye to the other eye—is probably
the most annoying. The aim of the current research is to
investigate how the two most important physical
quantities, contrast and binocular disparity, influence
crosstalk perception. Images consisting of a single
character and varying in contrast and disparity were
computer-generated to measure crosstalk visibility and
acceptability thresholds for two stereoscopic displays;
one display was based on active shutter glasses, and the
other on passive glasses. Results show that, under the
same experimental condition, there is no significant
difference in crosstalk perception between both 3-D
display technologies. Crosstalk annoyance increases with
increasing contrast and disparity, i.e., less crosstalk
is allowed for higher levels of contrast and disparity.
Based on the experimental results, an analytical formula
for predicting crosstalk perception is proposed.
