Comparing levels of crosstalk with red/cyan, blue/yellow, and green/magenta anaglyph 3D glasses

Abstract

The Anaglyph 3D method of stereoscopic visualization is both cost effective and compatible with all full-color displays, however this method often suffers from poor 3D image quality due to poor color quality and ghosting (whereby each eye sees a small portion of the perspective image intended for the other eye). Ghosting, also known as crosstalk, limits the ability of the brain to successfully fuse the images perceived by each eye and thus reduces the perceived quality of the 3D image. This paper describes a research project which has simulated the spectral performance of a wide selection of anaglyph 3D glasses on CRT, LCD and plasma displays in order to predict ghosting levels. This analysis has included for the first time a comparison of crosstalk between different color-primary types of anaglyph glasses - green/magenta and blue/yellow as well as the more traditional red/cyan. Sixteen pairs of anaglyph 3D glasses were simulated (6 pairs of red/cyan glasses, 6 pairs of blue/yellow glasses and 4 pairs of green/magenta glasses). The spectral emission results for 13 LCDs, 15 plasma displays and one CRT Monitor were used for the analysis. A custom written Matlab program was developed to calculate the amount of crosstalk for all the combinations of different displays with different anaglyph glasses.
