Persistence of Vision

 Persistence of Vision

Persistence of vision is the key to how see view things in animation, film, video or computer games. With animation, film, video and computer games, the images on the screen do not actually move. What you are actually seeing on the screen is a number of still images, slightly different from the last playing one after another in a sequence. (no less than 1/12th of a second). When the images are played back to you, the eye can not actually tell it a sequence of pictures because the brain and eyes are tricked so that you think that it is moving because they are moving faster one after the other so your brain cannot process them quick enough.

Persistence of vision has been around about 7000 years in ancient china. Also in the Victorian times there was a love for novelty and inventions. There was many toys and gadgets that was made in that age that used the process of persistence of vision.

A Zoetrope is a drum shape with an open top so you can put a piece of paper inside of it with 12 pictures on, each pictures is very different from the last. There are also 12 slots in the sides of the drum where if you look in to them as it is spinning it looks like the pictures inside of the drum are moving around. This is the illusion that it the pictures are moving.
