大きな両眼視差領域における運動視差による立体視の促進効果

抄録

This study examined the cue integration of retinal disparity and motion parallax by measuring perceived depth in the large range of disparity (9’to 390’) when both cues were available at the same time and when only one of these cues was available. The test stimulus presented on a computer monitor was a gray disc, 2 deg in diameter, surrounded by a random-dot pattern as a reference. The observer reported an extent of apparent depth by manually adjusting distance between two rods. The results showed that when both cues were available the perceived depth was much larger than that when only one of these cues was available in the large disparity conditions (>around 90’), suggesting nonlinear interaction between disparity and motion parallax cue processing.
