When watching stereoscopic three-dimensional (S3D) display, most people will feel visual discomfort due to the color asymmetry of left and right eyes. However, a stereo pair consisting of one gray image and one color image can be perceived by a human observer as a 3D color scene, and there is no depth perception degradation and only limited color degradation. This novel presentation approach of stereoscopic display can reduce the redundancy of color information, optimize the video compressions and greatly save the transmission bandwidth. And it may also alleviate the visual comfort problem of asymmetric color stereoscopic content by reducing the visual system load. In this paper, visual comfort was evaluated for stereoscopic videos with different gray-color allocation schemes. Three allocation schemes are used to investigate the changes of visual comfort of stereoscopic video. The subjective evaluation results show that different binocular color allocation schemes have an impact on the visual comfort assessment (VCA) scores. Among them, the binocular color coding of the left half of all frames in stereoscopic video are color and the right half of all frames are gray, which may reduce the amount of color information processing by the visual brain and therefor has a more comfortable visual experience. We suggested that the color allocation scheme also can reduce the flicker of video, and the visual comfort of stereoscopic contents with only half color information is We demonstrated that this color allocation scheme also can reduce the flicker of video, and the visual comfort of stereoscopic contents with only half color information is within the acceptable range.
