persistance of vision

persistance of vision is where your brain is tricked into thinking that an object is moving in a way that it is not basically  mind trickery above is a video that show cases that :) Narrowly defined the theory of persistence of vision is the belief that human perception of motion brain centered is the result of persistence of vision eye centered That version of the theory was disproved in 1912 by Wertheimer
but persists in citations in many classic and modern film-theory texts In drawn animation moving characters are often shot on twos that is to say one drawing is shown for every two frames of film which usually runs at 24 frames per second

    It is good to complete the class task, but at this level we would expect a more detailed description, such as the definition at the end of these comments. Watch out for spelling mistakes.

    Persistence of vision should be more accurately described as "when a sequence of still images each with very slight successive changes is played back, the brain tends to fill in the gaps between each image, and sees the sequence as a continuous movement rather than as a series of still images. This is the method used in animation and video to give the illusion of movement. Persistence of Vision works with images between 8 images or frames per second through to 30 images or frames per second."
