Perception of Movement

Stroboscopic motion is also an illusion of apparent motion.  However, unlike the phi phenomenon, stroboscopic motion is created when series of still images are rapidly flashed one after another, so it appears that an object is moving.  Stroboscopic motion is evident in a series of still photos taken of a dancer in different positions.  When quickly shown an image of each individual pose, the dancer appears to be moving.
