Abstract
This paper discusses the effect of brightness contrast
on stereoscopic 3D (S3D) perception from a
psychophysical viewpoint. It considers the way in which
S3D perception is influenced by different decisions of
brightness contrast, and identifies the thresholds of
S3D perception in several brightness adjustments,
which can provide guidance during colouring decisions
for S3D imaging. In particular, different levels of
brightness are tested on foreground and background
objects to build brightness contrast in computer graphic
scenes. Psychophysical trials are utilized to examine the
thresholds of observers’ depth perception. A polarised
projection system is built for stereoscopic viewing and
the image stimuli are rendered from stereoscopic
virtual cameras by renowned 3D film making
programme during experiments. The data indicates that
it was able to provide a significant effect over the
brightness adjustments in controlling the perceived
depth in stereoscopic perception, and darker object in
foreground with brighter object in background result
stronger stereoscopic 3D perception.
