Animation is based on which principle of human vision?

• A. Persistence of vision
• B. Frame persistence
• C. Motion persistence
• D. Continuity of vision

Answer: (A)

Animation relies on our visual system turning a rapid sequence of still images into smooth motion. This illusion comes from persistence of vision: the image on the retina lingers for a brief moment after a frame changes, so the next frame blends with the previous one instead of appearing as a quick flash. Show frames fast enough—typically around 24 frames per second or higher—the lingering image combines with the next frame to create continuous motion rather than a strobe of separate pictures. That temporal integration is the reason animation looks fluid. Other terms aren’t the standard explanation for this effect. Frame persistence and motion persistence aren’t commonly used concepts to describe how we perceive moving images, and continuity of vision doesn’t capture the specific temporal blending that makes sequences appear seamless.
