The purpose of this research is to clarify the effects of binocular parallax in 360-degree images. Specifically, we measured and analyzed gazes during viewing stimuli for 60 seconds with different parallax distributions. The parallax distributions were four types of all 2D / all 3D / left and right 3D / front and back 3D. From the results, it was suggested that disparity distributions changed the viewing behavior with the passage of time, and even if parallax is added to a part of the image, the subjective stereoscopic effect increased. From these facts, it is suggested that there is effective 3D representation in the 360-degree images.
