Abstract

The ghost image induced by System-Crosstalk (SCT) of 3D display, due to optical hardware imperfections, is the major factor to jeopardize stereopsis. The system crosstalk can be measured by optical measuring instrument and describes the optical leakage from the neighboring viewing zones. The amount of crosstalk reduces the ability of the viewer to fuse the stereo-images into 3D images. The Viewer-Crosstalk (VCT), combined with hardware and content issues, is an overall evaluation of the ghost image and can be easily interpreted based on the principle of binocular 3D display. The examination of different SCT values was carried out with a seven-grade subjective evaluation test. In our previous study, it was shown that many other factors, such as contrast ratio, disparity and monocular cues of the images, play important roles in the stereopsis. In this paper, we study the factors of stereo-images with different crosstalk levels that may affect stereopsis. For simulate the interference between stereo-images, digital image processing are employed to assign different levels of crosstalk to each other at properly specified disparity between images. Results of this research can provide valuable reference to the content makers and for the optimized design of 3D displays with minimum System Crosstalk.
