Crosstalk characterization method for stereoscopic three-dimensional television

Abstract

A crosstalk characterization model is proposed that shows the relationship between colors with and without crosstalk by using CIE tristimulus values. The proposed model is based on the 3D color measurement results of two different stereoscopic 3D televisions with shutter glasses, namely, a PDP and an LCD. The PDP exhibits a significant dependence of crosstalk on channel and tristimulus values, meaning that different channels and wavelengths result in different degrees of crosstalk, while the LCD exhibits little channel or wavelength dependence. Moreover, for PDP, the proportion of leaked light increases as the luminance of the opposite view decreases. In spite of different crosstalk characteristics, both PDP and LCD show similar performance resulting in 1.5ΔE* <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ab</sub> and 1.9ΔE* <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ab</sub> average color difference between the measured and the predicted. The proposed model could be used to develop a better crosstalk metric or a crosstalk cancellation algorithm by more accurately predicting colors including crosstalk.
