This paper describes a study that focuses on disparity changes in emotional scenes of stereoscopic (3D) images, in which
an examination of the effects on pleasant and arousal was carried out by adding binocular disparity to 2D images that
evoke specific emotions, and applying disparity modification based on the disparity analysis of famous 3D movies.
From the results of the experiment, for pleasant, a significant difference was found only for the main effect of the
emotions. On the other hand, for arousal, there was a trend of increasing the evaluation values in the order 2D condition,
3D condition and 3D condition applied the disparity modification for happiness, surprise, and fear. This suggests the
possibility that binocular disparity and the modification affect arousal.
