We have analyzed the inter-saccade intervals during binocular gaze at a brightness edge, a depth discontinuity edge, or a rim; right and left retinal images match in the edge, but not due to occlusion in the rim. In the case of edges, the histograms of the intervals are unimodal and have the same distribution, not depending on the existence of texture. In contrast, the histograms for the rim show clear differences depending on the existence of texture; the histograms in the case of no texture are similar to that for the edges, but the histograms in the case of texture are bimodal and tend to shirt toward lower value of the interval. We have conjectured that the saccade planning schema may include a, mechanism in the early stage of visual processing, which detects occlusion by matching both retinal images and causes earlier saccades.
