55.4: Image Processing‐based Crosstalk Reduction for Stereoscopic Displays with Shutter Glasses

Abstract

We propose a crosstalk reduction method based on image processing for stereoscopic displays with shuttered glasses. The proposed method precisely evaluates crosstalk caused by not only LCD responses but also backlight leakage and glasses responses. Experimental results show that our method reduces crosstalk by 70% whereas that of a previous work which evaluates only the LCD responses was 65%.

71.4: A Simulation Method of Time‐Sequential Stereoscopic Effect with Various LC Response Speed on Motion Pictures

“…For more cases, backlight and glasses driving scheme also affect the crosstalk as well and crosstalk could be very low. [6] [8] [10] Here we base on the case that LC speed dominates crosstalk, and simulate the crosstalk of 120hz time-sequential 3D display without black insertion. About the LC response time of the display, we base on the measured 16*16 grey-to-grey levels data and apply the crosstalk reduction method to evaluate the 256*256 crosstalk values of each level.…”

“…[4] Konrad et al [5] presented a model for intensity leak for a time-sequential LCS/CRT system to eliminate the crosstalk by a computationallyefficient algorithm and study the trade-off between crosstalk elimination and image contrast. A crosstalk reduction method for time-sequential shutter-glasses 3D was proposed by Iwanaka et al [6] which could reduce crosstalk by 70%. According to these studies, one could reduce crosstalk to human perceptible level, but with the limitation of LC properties, not all crosstalk could be reduced well.…”
