What phenomenon explains why moving pictures appear to move when images are shown in rapid succession?

• A. Persistence of Vision
• B. Frame Delay
• C. Motion Blur
• D. Visual Persistence

Answer: (A)

Persistence of vision explains why moving pictures appear to move when frames are shown rapidly. The eye retains a visual image for a brief moment after it’s shown, so when the next frame appears before that image has faded, the brain blends the two together. Displaying many frames per second—like standard film rates—lets successive images merge into smooth motion rather than a flicker of still pictures. This is why you perceive continuous movement from a sequence of individual frames. The other terms describe different ideas (frame timing, exposure-related blur, or a similar-sounding term) but they don’t capture the same mechanism that makes rapid sequences read as motion.
