Persistence of Vision is a phenomenon where the human eye retains an image for a fraction of a second after the source has disappeared. This effect allows us to perceive a series of still images as continuous motion. It is a key principle behind how we experience films and animations, as our brain fills in the gaps between frames. This concept is crucial in the creation of motion pictures and animation. By displaying a rapid sequence of images, typically at 24 frames per second or more, our eyes and brain combine these images into a smooth, flowing visual experience, making it seem as if the images are moving.
