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.
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .
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 semi-automatic system using vertical spools that can hold an entire movie, however these are not the continuous loop projection systems and the film will need to ...
A frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream. It is usually employed as a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored, transmitted, analyzed, or combinations of ...
Comparison of a slow down video without interframe interpolation (left) and with motion interpolation (right) Motion interpolation or motion-compensated frame interpolation (MCFI) is a form of video processing in which intermediate film, video or animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display ...
In contrast to the still camera, which captures a single image at a time, the movie camera takes a series of images by way of an intermittent mechanism or by electronic means; each image is a frame of film or video. The frames are projected through a movie projector or a video projector at a specific frame rate (number of frames per second) to ...
A video projector is an image projector that receives a video signal and projects the corresponding image onto a projection screen using a lens system. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp ), Xenon arc lamp , metal halide lamp , LED or solid state blue, RB, RGB or fiber-optic lasers to ...
Three frames of 9.5 mm film showing central sprocket holes. 9.5 mm film is an amateur film format introduced by Pathé in 1922 as part of the Pathé Baby amateur film system. It was conceived initially as an inexpensive format to provide copies of commercially made films to home users, although a simple camera was released shortly afterwards.
