Study on the Effect of Relative Disparity and Horizontal Position of Two Lines of 3D Subtitles on Visual Comfort

摘要

The aim of the present experiments is to study the effect of relative depth and horizontal position of two lines of subtitles in 3D films on stereoscopic visual comfort. The study included two experiments. In the experiment 1, it mainly studied the influence of the relative disparity of two-line 3D subtitles on visual comfort. The results showed the relative disparity of two-line subtitles was +42.64 arc min that was more comfortable for the viewers. And In experiment 2, the study was on the effect of the relative horizontal displacement of the two lines of subtitles on visual comfort. The results showed the horizontal position of two-line subtitles had no effect on visual comfort.
