近年来，已经开发了产生诸如多目图像序列的多视点图像的立体显示器。这些显示器提供运动视差作为深度提示。本研究旨在研究纸板效应，即，在传统双目立体显示器中观察到的视觉失真通过运动视差得到改善。显示纸板效应的列图像被显示给受试者。指导受试者调整平面半圆的曲率，以量化显示列的曲率。对于运动视差，将运动视差的存在或不存在、头部移动的存在或不存在以及柱的速度设置为变量。对于双眼视差，将幅度设置为变量。结果表明，纸板效应的改善率的条件下，允许被试操作的运动视差和双眼视差高于条件下，允许被试操作的双眼视差。没有观察到头部移动或柱速度差异的存在或不存在的显著影响。这些结果表明，在多视点立体显示器中再现的运动视差改善了纸板效果。
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.
