Abstract
Abstract3D visual comfort can be influenced by such common factors as binocular parallax, 3D image contrast, viewing distance, and illumination condition. This paper investigates the effect of contrast enhancement and illumination condition on 3D visual fatigue by performing a visual fatigue measurement experiment, of which subjects need to watch 3D images under two illumination conditions and finish a comfort judgment task. The proportion of discomfort images, the subjective evaluation of visual fatigue under 100 lux and 500 lux illumination conditions, the effect of image contrast enhancement on 3D visual fatigue, and the relationship between visual fatigue and proportion of discomfort images were analyzed, respectively. The experimental results showed that both the contrast enhanced by Laplacian algorithm and low illumination condition have positive influence on 3D visual perception of eyes; the 3D visual fatigue of contrast enhanced by Laplacian algorithm under low illumination condition was less than other situations in the experiment. Moreover, it was examined that the proportion of discomfort images can be potential prediction indicator of the 3D visual fatigue.
