抄録

Stereoscopic displays that produce multiple viewpoint images, such as multiocular image sequences, have been developed in recent years. These displays provide motion parallax as a depth cue. The present study was conducted to examine if the cardboard effect, i.e., the visual distortion observed in conventional binocular stereoscopic displays, is improved by motion parallax. Column images that show the cardboard effect were displayed to subjects. The subjects were instructed to adjust the curvature of a plane half circle to quantify the curvature of the displayed column. For motion parallax, the presence or absence of motion parallax, the presence or absence of head movement, and the velocity of the column were set as variables. For binocular disparity, the magnitude was set as a variable. The results showed that the cardboard effect improvement rate under the condition that allows subjects to operate both motion parallax and binocular disparity was higher than that under the condition that allows subjects to operate only binocular disparity. No marked effect by the presence or absence of head movement or the difference in velocity of the column was observed. These results suggest that motion parallax, which is reproduced in multiple viewpoint stereoscopic displays, improves the cardboard effect.
