A movie projector (or film projector) is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors (see also digital cinema).
Quite often these spools will be located some way from the projector and the film path may be over rollers along the ceiling of the projection room and surrounds. The lenses of the projector can be automatically rotated in front of the projector light aperture to accommodate the correct lens for a given format. The picture to the right shows a ...
English: Bill tears apart a film projector to reveal the amazing mechanisms used in the pre-digital age to trick the mind into seeing a moving image. He uses high speed photography and animations to show how the projector moves the film intermittently, how a shutter strategically blocks light as the film moves, and how the photo sensor reads the sound.
In the early 1980s–1990s, overhead projectors were used as part of a classroom computer display/projection system. A liquid-crystal panel mounted in a plastic frame was placed on top of the overhead projector and connected to the video output of the computer, often splitting off the normal monitor output.
The film gate is the rectangular opening in the front of a motion picture camera where the film is exposed to light (or an opening for showing the film with a projector). The film gate can be seen by removing the lens and rotating the shutter out of the way. The film is held on a uniform plane at a calibrated distance in the gate by a pressure ...
A pair of cue marks is used to signal the projectionist that a particular reel of a movie is ending, as most movies presented on film come to theaters on several reels of film lasting about 14 to 20 minutes each (the positive print rolls themselves are either 1,000 feet or, more commonly, 2,000 feet, nominally 11.11 or 22.22 minutes, absolute ...
the Latham loop in this projector's film path is seen above the lens, coming out of the feed sprockets at top center The Latham Loop is used in film projection and image capture. It isolates the filmstrip from vibration and tension, allowing movies to be continuously shot and projected for extended periods.
The most complex part of telecine is the synchronization of the mechanical film motion and the electronic video signal. Every time the video (tele) part of the telecine samples the light electronically, the film (cine) part of the telecine must have a frame in perfect registration and ready to photograph.
