The Geneva mechanism is an essential component of many film projectors which works in concert with other projector components such as the shutters/shutter and intermittent sprocket in order to transform a film strip composed of static pictures into what appear to be "moving images". It is a mechanism which converts rotational motion into periodic motion.
