Abstract
Vertical fusion amplitude (VFA) as a reference to assess visual
tolerance for vertical disparity is measured by various methods. However,
it has not been comprehensively investigated on current 3D displays,
although some technical display features lead to different visual
impacts, such as crosstalk and viewing angle. A psychophysical measurement
of the VFA on representative 3D stereoscopic and autostereoscopic
displays is presented here, with considerations on certain factors
affecting visual performances. For the 3D stereoscopic display, we
used a 3D projector, VFA was measured under different viewing distance,
stimulus size, background luminance, room lighting, target complexity
and disparity velocity. Corresponding tests were carried out on a
lenticular autostereoscopic TV, with additional test parameters of
viewing angle, due to the presence of the lenticular. Results show
that the vertical disparity tolerance is generally better on 3D projector
than on autostereoscopic TV. VFA on 3D projector is significantly
affected by the stimulus size, target complexity and disparity velocity,
whereas crucial factors for autostereoscopic TV are stimulus size,
target complexity, disparity velocity, background luminance and viewing
angle. The visual performance differences indicate that technical
display features should be considered when VFA is measured on different
3D devices.
