Persistence of Vision

 

PERSISTENCE OF VISION: WHAT IT IS/HOW IT WORKS.

Persistence of vision is a theory which attempts to explain how the human eye/brain can be fooled into seeing continuous motion when presented with a sequence of still images (film or video frames) at a rate of 10 frames per second (fps) or greater.

Furthermore, television and movie technologies have used this effect to deceive us into perceiving continuous motion, where there is none. This is of course done by displaying a series of still images (snapshots or frames) in fast succession. 10 fps is regarded as a minimum to produce the illusion of continuous motion but a frame rate of 24 is preferable because it prevents the image from being jerky.

Here is a short video explaining how you can use persistence of vision in many different ways :
