A video projector takes a video signal and projects the corresponding image on a projection screen using a lens system.
All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies
through manual settings. Video projectors are widely used for conference room presentations, classroom training, home theatre and live events
applications. Projectors are widely used in many schools and other educational settings, connected to an interactive white board to interactively
teach pupils.
A movie projector is an opto-mechanical device for displaying moving pictures by projecting them on a projection screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras.
A slide projector is an opto-mechanical device to view photographic slides. It has four main elements: a fan-cooled electric light bulb or other light source, a reflector and "condensing" lens to direct the light to the slide, a holder for the slide and a focusing lens. A flat piece of heat absorbing glass is often placed in the light path between the condensing lens and the slide, to avoid damaging the latter. This glass transmits visible wavelengths but absorbs infrared. Light passes through the transparent slide and lens, and the resulting image is enlarged and projected onto a perpendicular flat screen so the audience can view its reflection. Alternatively the image may be projected onto a translucent "rear projection" screen, often used for continuous automatic display for close viewing. This form of projection also avoids the audience's interrupting the light stream or bumping into the projector.
An overhead projector is a variant of slide projector that is used to display images to an audience.
