The discontinuity of motion parallax offered by multi-view displays was assessed by subjective evaluation. A super multi-view head-up display, which provides dense viewing points and has short-, medium-, and long-distance display ranges, was used. The results showed that discontinuity perception depended on the ratio of an image shift between adjacent parallax images to a pixel pitch of three-dimensional (3D) images and the crosstalk between viewing points. When the ratio was less than 0.2 and the crosstalk was small, the discontinuity was not perceived. When the ratio was greater than 1 and the crosstalk was small, the discontinuity was perceived, and the resolution of the 3D images decreased twice. When the crosstalk was large, the discontinuity was not perceived even when the ratio was 1 or 2. However, the resolution decreased two or more times.
