Binocular depth perception for moving images

It is important to know how motion affects on the perception of depth when we present moving images on a three dimensional display. Effect of motion on binocular depth perception has at least three aspects. First, difference in image motion provides the difference of temporal frequency contents of stimulation that perhaps influences the depth perception. Second, the mechanism of motion analysis may interact with that for the binocular depth perception. Third, temporal changes of monocular and binocular depth cues provide the information of motion in depth. Psychophysical studies related to these aspects have revealed the importance of consideration of motion signals for depth processing in the visual system. Reviewing these studies, we discuss possible interactions between motion and depth perception, in addition to the general effect of temporal characteristics of moving stimulus. We also discuss the possible contribution of variety of depth cues to motion in depth perception.
