The movie camera is a type of photographic camera which takes a quick sequence of photographs on film; once developed this film can be projected as a action picture. In contrast to a still camera which captures a single picture at a time, the movie camera takes a sequence of images, each called a Frame. This is accomplished through an constant mechanism. The frames are later played back in a movie projector at a specific speed, called the "frame rate" to give the illusion of motion. Our eyes and brain merge the separate pictures together to create the illusion, a phenomenon called the "persistence of vision".
Most of the ocular and mechanical rudiments of a movie camera are present in the movie projector. The camera will not have an illumination source and will keep its film stock in a light-tight enclosure. A camera will also have revelation control via an iris aperture located on the lens. Otherwise, the requirements for film tensioning, take-up, alternating motion, loops, and rack positioning are almost identical.
