Definitions for "Motion parallax"
when in motion, objects at different distances from the observer move at different velocities on the retinal surface, which can be utilized to code relative depth.
A depth cue provided by the fact that, as an observer moves, the images cast by nearby objects move more rapidly on the retina than the images cast by objects farther away.
monocular visual cue for estimating depth of moving objects by noticing how closer objects appear to move more than distant ones when the observer moves
