The rapid display of related still images is the basis of which animation principle?

• A. Motion Blur
• B. Persistence of Vision
• C. Frame Interpolation
• D. Onion Skinning

Answer: (B)

Persistence of vision explains why showing a rapid sequence of related still images appears as smooth motion. The eye retains a brief afterimage, so each picture blends with the next when shown quickly, creating the illusion of continuous movement—this is the fundamental reason traditional animation and film work. Motion blur describes a streaking effect from exposure time, not the perceptual basis for motion from stills. Frame interpolation is a digital method to add frames between originals, and onion skinning is a drawing aid to view multiple frames simultaneously; neither describes how we perceive rapid image sequences as motion.
