Abstract
We compared visual fatigue caused by HDTV and stereoscopic HDTV at the viewing distance of 4.5 m. We measured the degree of visual fatigue using a subjective test method and compared it to an objective measure, namely the change in accommodation before and after viewing images. We also detected visual discomfort image scenes from the best program using the single stimulus continuous quality method. As a result, the mechanism between convergence eye movement and the accommodation function in the depth of focus in addition to conflict of convergence eye movement and accommodation function appears to affect visual fatigue. From the examination between the results of single stimulus quality evaluation and the feature characteristics of test stereoscopic images, we found that a local low subjective evaluation appeared for both high degree of parallax and amount of motion in the test stereoscopic images. But motion components were very small, the subjective evaluation value was rarely very low.
