Schematic illustration of motion in depth and the associated image motion. A, Motion of an object directly toward the cyclopean eye produces opposite directions of image motion in the two eyes. In addition, the horizontal binocular disparity changes over time as the object moves in depth. B, Receding movement of an object reverses the direction of image motion in each eye and reverses the temporal sequence of changes in binocular disparity.
