“…It was reported that the perceptual impact of excessive demand on the AC linkage is related to visual discomfort [1,9]. Yano et al [14] concluded that the visual fatigue occurred when the MOTION-IN-DEPTH IN STEREOSCOPIC 3D VIDEO stereoscopic images involved motion-in-depth even if they were displayed within the range of depth of field. Meanwhile, no visual fatigue was found in lateral-motion images.…”

The motion-in-depth is an important factor in measuring visual discomfort when watching stereoscopic 3D video since it changes accommodation and vergence at the same time. In this paper, we examine visual discomfort caused by motion-in-depth in terms of viewing time and display size in watching stereoscopic 3D video. The assessment methods for visual discomfort we used were a subjective test such as a questionnaire, and an objective test such as eye blink rate detection. The experimental results showed that visual discomfort increased in proportion with the speed of motion-in-depth and viewing time. We also found that the viewer's discomfort increased when watching stereoscopic 3D video on the smaller-sized display than on a larger-sized display.

Abstract-The complexity of the world is a factor of evaluating the visual fatigue of 3D video. Depth discontinuities are the layers of the world and can be a characteristic of the complexity of the world. We suppose a new method to extract a depth discontinuities from a disparity map. We employed DIP algorithm for extraction of the depth discontinuities with a learned threshold automatically inferred based on the average and standard deviation of the disparity, that is, depth of the stereoscopy.Index Terms-Depth discontinuities, DIP, disparity map, human visual fatigue.

“…Recently, the commercial success of 3D contents leads to the rise of 3D related markets for various 3D devices, such as 3DTV, 3DVR and 3D cameras [1][2][3][4][5][6]. Also, as 3D cameras become cheaper and smaller, it is possible for users to buy a dual lens stereoscopic camera and make 3D video contents easily.…”

In a dual lens stereoscopic camera, a convergence point determines the stereopsis effects of a video. When a user zooms an object, a convergence point is fixed since it is not coupled with a zoom function. Due to the fixed convergence point, it is possible for a zoom to cause the excessive binocular disparity resulting in visual discomfort. In this paper, to solve this problem, we build the relational model including all phenomena possible to arise and propose the adjustment methods of a convergence point by the positions of a focus, an object and a convergence point. We also evaluate the experiments measuring a binocular disparity and the subjective test to investigate the visual comfort. The results show that one of the proposed methods produced more comfortable 3D images to viewers than the others.
