Abstract
Crosstalk between the left-eye and right-eye images
is one of the main artifacts affecting the visual quality of stereoscopic
liquid crystal display (LCD) systems. In this paper, a novel technique,
called Optimal Backlight Modulation (OBM), is proposed to reduce crosstalk
by taking the advantage of newly emerged light-emitting diode (LED)
backlight panel. Unlike most existing techniques which solely aim
at eliminating the effect of crosstalk, ignoring image brightness
and contrast, OBM strikes a better balance by maximizing the output
luminance while confining the crosstalk within a given level. A simple
closed-form approximation of the optimization problem can be easily
employed and solved in real time on LCD control hardware. Simulation
results show that the proposed OBM algorithm provides the same or
higher luminance while reducing the crosstalk by 60% compared with
the other tested methods.
