The effect of stereoscopic display luminance and ambient illuminance on physiological measurement and image quality

Abstract

When people watch 3D-Ready TV, the display luminance as well as the ambient illuminace is important factors for image quality and physiological comfort. In this research, a human factors experiment on a stereoscopic display was conducted. The result showed that display luminance affected subjective comfort evaluation and image quality evaluation. The effect of ambient illuminance also influenced objective asthenopia index (CFF), subjective comfort evaluation and viewers' image quality evaluation of watching 3D static pictures. However, the main effects of display luminance, ambient illuminance, and their interaction effect were not significant on objective physiological measurement (HRV). Among the six combination levels of display luminance and ambient illuminance, viewers felt more comfortable and got the best image quality in the high levels of display luminance and ambient illuminance. The outcome of the experiment is expected to find out the optimal display luminance and ambient illuminance combination level for designers' guidelines and users' references as viewing 3D displays.
