HOW WE SEE THE THINGS OR PERSONS MOVING IN A MOVIE?

Persistance of vision is the property of vision due to which the sensation of image formed on retina of our eyes persists in our brain for 1/10 sec. If any other image is formed on retina before that then we are unable to differentiate between those images.
This property of vision is called persistance of vision.

Persistence of vision is the commonly used term to describe the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films.

Here are 9 still pictures of a man riding on the horse. When these pictures are run fast continuously with a speed greater than 16 frames/sec then the effect is as shown in gif image.
