Projector is a package for RS-232 control/automation of Electrohome Marquee series CRT projection systems. It provides a simple command line tool for controlling various features of an RS-232-based "network" of Marquee projectors.
an optical instrument which projects an image from a transparency or an opaque image onto a projection screen or other surface, using an intense light and one or more lenses to focus the image. The term projector by itself is usually used for projection of transparent images by passing the light beam through the image; a projector which projects an image of an opaque object is now ususally referred to as an overhead projector. In projection of this latter form the projection is accomplished by means of a combination of lenses with a prism and a mirror or reflector. Specific instruments have been called by different names, such as balopticon, radiopticon, radiopticon, mirrorscope, etc.
A device that attaches to your computer to project your presentations onto a large screen.
Projectors fall into two categories, those that project the image onto the front (viewed) surface of a reflective screen and those that project onto the rear surface of a translucent screen. Both types can be based on CRTs, LCDs (liquid crystal displays), DMDs (digital micromirror device from Texas Instruments, also known as DLP) or some other technology. Of all of these, CRTs are the most improved with a line doubler. The effect on LCD and DMD projectors greatly depends on the make and model of the projector - with some there is a dramatic improvement, with others it is not as dramatic.
The term 'video projector' is used loosely at ClassTech to describe any piece of equipment that displays a video or computer source on a projection screen. 'Computer projector' refers specifically to the newer video projectors that can handle the higher resolutions necessary for computer support.
A device that combines light, an optical system, electronics, and a display for projecting an image from a computer or other source onto a screen.
an optical device for projecting a beam of light
an optical instrument that projects an enlarged image onto a screen
a delicate device that can have its LCDs misaligned when not handled properly
a device that combines a light
a glass ball that focuses the intense light of an HID bulb directly onto the road and away from the easily irritated eyes of other drivers
an apparatus for projecting images onto a large size screen by optical projection
Projectors are used for the purpose of achieving a large screen size by projecting an image onto a wall/screen from a video device or a computer. The projector achieves this by integrating a light source, optics system, electronics and displays. Attached to a computer or video, it projects whatever the image is from the selected input. There is wide availability of projector products, differentiated by resolution, features and performance.
There are two ways to get an image on a screen. Shine light through an image forming element, or let light reflect from an image forming element. Both are very common. CRT projectors use an electron beam from behind and LCD devices rely on transmitted light to create the image, which is then communicated to a screen by lenses. Light valve ( ILA), and D_ILA/LCOS devices rely on light reflecting off an image element, which is then focused on a screen using lenses. See: Light Valve, ILA, D-ILA, LCOS, CRT.
An apparatus for projecting a picture on a screen. Whether the device is an overhead, slide projector, or a film projector, it is usually referred to as simply a projector.
A projector is a device that integrates a light source, optics system, electronics and display(s) for the purpose of projecting an image from a computer or video device onto a wall or screen for large image viewing. There are hundreds of products available in the market and they are differentiated by their resolution, performance and features. These devices attach to a computer or video device, as you would connect a monitor.
Display that projects image onto a screen.
A device containing a light source, an optics system, and electronics that takes a signal from a computer, VCR, DVD, camcorder, or other video device and projects a large image onto a wall or screen for viewing by groups. Projectors generally use either LCD or DLP technology - see "DLP technology" and "LCD technology."
any piece of technology that uses light to magnify images and send them to a vertical screen for viewing. CMO uses four types of projectors- overhead projectors, digital projectors, slide projectors, and document cameras. [click on each type of projector to see its definition and uses
A device used to enlarge images by focusing light through them onto a flat surface.
apparatus used to display enlarged still or moving images on to a screen.
A device for displaying a reel of a movie on a screen, either for a screening or a back projection.
