Color saturation (the amount of color)

Color control is common on almost all types of displays. Color control usually adjusts the total amount of color present in an image. This is also referred to as an image's color saturation. Saturation of color that indicates the proportion of white that has a certain color. The saturated colors are vivid and intense, while the mix are a little

CRT

A CRT projector is a video projector that uses a small, high-brightness CRT (or picture tube) as the image generating element. The image is then focused and enlarged onto a screen using a lens kept in front of the CRT face. Most modern CRT projectors are color and have three separate CRTs (instead of a single, colour CRT), and their own lenses to achieve

Chroma

Color information of a signal, related to the tone and saturation but not with the brightness or luminance of the signal. The black, gray and white have no chrominance, but any colored signal has both chrominance and luminance. A video picture can be seen to be made up of two elements, the chroma made up of colour information and the luminance made up of

Compression

Many projectors capable of projecting images with resolutions higher than his right. Just skip lines and columns. As the image quality is affected, many manufacturers have been devoted to improving special compression methods. Virtually all projectors and plasma screens have the ability to accept higher resolution inputs than they are designed for (the

Cinemascope

TV broadcast with a black stripe on the top and one on the bottom when playing on a conventional 4:3 screen. Widescreen televisions in the image may extend cinemascope is to completely fill the screen without losing so part of the picture. Peering into an anamorphic lens shows that it magnifies (projection lenses), or compresses (camera lenses) the image

Color bars

Video signal formed by a series of 8 bars colored (white, yellow, cyan, green, magenta, red, blue and black). It is used as a  reference for adjusting brightness, contrast, color intensity and color balance. Normally generated electronically. Color saturation and tint for NTSC video signals can be calibrated with saturation and hue adjustments. (PAL

CRT (cathode ray tube)

A CRT (picture tube ") is a specialized vacuum tube in which images are created when an electron beam travels up and down along the rear of a phosphor coated screen. Each time the beam passes through the screen lights up a horizontal line of  points of phosphorus inside the glass tube. To quickly draw hundreds of these lines from top to the bottom

Contrast ratio

Measures the difference between the brightest whites and blacks darker that can display a screen. The higher the contrast ratio, the greater the ability of a display to show subtle color details and tolerate ambient light in the room. The contrast ratio is an important specification for all types of TV screen, but especially for front projectors. Associated

Comb Filter

The task of a "Comb Filter" is to remove the residual chrominance (color) of the luminance signal (brightness). The "Comb Filter" improves the fine detail, clean contours of the images and deletes extraneous colors. Comb filters are designed to clean up any fuzziness or artifacts brought in by the composite signal. Comb filters use

Chrominance

Chrominance is the color component of a video signal that includes information on tint (hue) and saturation (intensity). Color is a three dimensional quantity and can be represented in many ways. We will be using two different representations. In the perceptual representation, color is defined by its luminance (or radiance)  and chrominance. The one-

CableCARD ™

A card security available on the providers of cable TV. It allows a TV with CableCARD option, to receive digital cable programming, including premium and HD channels, without using a separate box. The FCC (Federal Communications Commission) began to require cable service providers to make available the card CableCARD from July 1, 2004. CableCard makes your

Component video

This way of sending the video signal is to manage for multiple cables each of the 3 basic colors (RGB = Red, Green, Blue) with what is the best picture quality. This entry in the projectors have some with 3 RCA connectors (typically oriented film at home) and the other that is handled through the computer RGB input, using a special cable to become 3 RCA or

Command Wire

Generally a remote control (remote control) is wired, and uses an infrared transmitter. There are situations where it is not as practical: large rooms where the speaker is 35 feet or more from the projector. Rear projection, where the screen lets in a signal, but usually has a lot presented below. Also, the presenter has to point to the projector which

Composite video

It is the way to send a video signal which handled the elements of composite signal vertical, horizontal, and synchronization. This type of signal is used to send a video signal from a standard device to another, typically through a cable with RCA type connectors. Composite video can also be found as a video signal or video. It is the image signal that is

classic white or high contrast of gray?

There are two kinds of materials used to display most home theaters. One is the traditional white that has been used for decades, and another is a medium gray. The concept of a gray screen was introduced by Stewart Filmscreen with its product Grayhawk in 2001, and the gray screen has become very popular since then. The gray screens have been calls for high
