Abstract: To mitigate binocular rivalry involved in stereoscopic vision, and to alleviate the fatigue of an observer. In binocular vision, a fused point corresponding to a point b in a left visual image 320 is a point a of a right visual image 321. Since the left eye 200 and right eye 201 look at different objects, the binocular rivalry occurs when looking at the point b with the two eyes. Although the point b on the left visual image 320 is a sharp image, the point a on the right visual image 321 is an out-of-focus image. As a result, the image of the sharp point b is perceived first, and a subject B at the same distance is also perceived first. Thus, the out-of-focus point a and the image of the peripheral subject A become a removed image.
