Persistence of vision is when an image remains on the retina, like a
flash can leave a trace for a few minutes on your field of vision. If
persistence of vision were operating during the perception of a film,
each frame would stay impregnated on the retina. We would not
perceive the illusion of motion, but all the still frames
superimposing. The correct phenomenon responsible for the illusion of
motion in cinema is the Phi Phenomenon. The movement appears during
the black space between individual frames. If there is no
relationship between the images, as in a flicker film, then the
illusion will not be of motion but of flicker, for example.
