Abstract

The relationship between high frame rate and depth perception was investigated. Psychophysical experiments using moving random dot stereograms to study depth discrimination under several conditions showed that three-dimensional motion images produced and displayed with a frame rate of 240 fps enable finer discrimination of depth for the viewer compared with frame rates of 120 or 60 fps. In addition, overall evaluations of natural three-dimensional motion images by viewers confirmed that more natural motion and depth impressions were presented at 240 fps than at lower frame rates. Further, the results are discussed with reference to a recent theoretical model of the dynamic spatial frequency response of the camera/display system.
