A visual illusion where static images presented in quick succession create the perception of continuous movement. This phenomenon arises because the human visual system integrates discrete images into a fluid sequence when the time interval between presentations is sufficiently short. A common example is the perception of movement in motion pictures, where a series of still photographs projected rapidly onto a screen gives the impression of continuous action. Another manifestation occurs with sequentially illuminated lights, giving the impression of a single light source moving along a path.
This perceptual effect is fundamental to various technologies and fields of study. It underpins the operation of film, animation, and many types of displays, allowing for the efficient representation of dynamic scenes using static elements. Historically, its understanding has been crucial in the development of visual media and continues to inform research in psychology, neuroscience, and computer graphics. The efficiency with which the human brain processes visual information and constructs a sense of motion from discontinuous stimuli demonstrates its adaptive capacity and provides insights into the mechanisms of perception.
