VIEWING EXPERIENCE OF 3D MOVIE WITH SUBTITLES

Many people report visual fatigue and discomfort while watching 3D displays. This situation is aggravated when subtitles are involved. However, little concern has been given to the issue of how to properly place the subtitles in 3D movies. In our work, subjective assessment has been carried out for 3D movies, in order to find out how much in depth is the appropriate position for placing subtitles, and what the relationship between the appropriate position and the range of disparity in a 3D movie is. Experimental results show that when the disparity of subtitles is one or two pixels more than that of the scene objects which is put the closest to the viewers, the viewing experience is the best. On the other hand, the subjective score of a subtitled movie decreases with the increment of the range of disparity, given the same maximum disparity.
