continuous projector
Quick Summary
A projector is a device that enlarges images onto a screen. It uses a light source and lenses. Simple projectors display still images, like photos or slides, by passing light through them or reflecting light off them. Motion-picture projectors are more complex, using a shutter to flash individual frames from film onto the screen, typically at about 16 frames per second.
In television technology, a "continuous projector" is used in telecine to convert film to video signals. It employs a scanning spot that moves with the continuously advancing film, capturing the image and converting it into a video signal. This differs from an "intermittent projector," which holds each film frame stationary for a brief moment while light passes through it, similar to traditional cinema projectors.123
