The hue and saturation of a color. The chrominance signal is modulated onto a 4.43 MHz carrier in the PAL television system and a 3.58 MHz carrier in the NTSC television system.

The color of a video signal. Video signals are split into separate luma and chroma (color) components for higher-quality and more efficient transmission and encoding. The chroma signal is typically split into two components or color difference signals, such as YUV format. See also luminance.

refers to the color information of the overall video signal. Also see luminance, component video, and S-video. back to the previous page

The signal which carries the colour information in video.

The color information contained in a video signal separate from the luminance component, consisting of the hue (phase angle) and saturation (amplitude) of the color subcarrier signal. Changing the chrominance does not affect the brightness of the picture.

Chroma - the part of the S-Video signal that carries the color information

The color information in a television picture. Chrominance can be further broken down into two properties of color: hue and saturation. Also called chroma.

Color aspects of a picture.

The saturation and hue characteristics of a composite video signal; the portion of the video signal that contains color information. Adjust chrominance and other video levels before digitizing.

The color component of the video signal, denoted by the letter 'C' In high-band camcorders (Hi8, S-VHS and S VHS C),the video signal is split into luminance (brightness) and chrominance (color). Processing the two signals separately helps improve the picture quality and avoid effects such as moire patterning - the tartan-like interference seen on fine patterns in a scene.

The color parameters of an image. Usually represented by hue and saturation.

Portion of a video signal carrying color information.

The colour information of a television picture. It is also used to refer to the modulated colour component of a PAL, SECAM or NTSC television signal.

Portion of video signal that carries color information (hue and saturation, but not brightness); frequently abbreviated as "C," as in "Y/C" for luminance/chrominance. [See luminance.

The portion of a composite signal that carries color information. For example, the Cb or Cr component of a YCbCr signal represents part of a pixel's chrominance. ( See also luminance.)

The video signal carrying color information and is abbreviated as "C"

In television and video, a signal indicating both hue and saturation (Zelanski, Collins).

Saturation and hue characteristics of color television.

Portion of video signal that carries hue and saturation color information. Also see luminence.

the difference between any colour and a specified reference colour or equal brightness.

Refers to the hue and saturation of a colour.

The colour portion of the video signal - includes hue and saturation information but not brightness (see luminance).

color component of an image.

A colour component of an image.

The part of a composite video signal that contains the color information about the image.

The color information of a color video signal.

A color term defining the hue and saturation of a color. Often confused with brightness, the two terms are not interchangeable.

refers to the color components (hue and saturation) of a luminance-based representation of color.

The chrominance of a picture refers to its color saturation and hue.

The part of a colour video signal that carries the colour information.

Color portion of a video signal.

The portions of a signal that are dedicated to describing the hue and saturation. Used in measuring the difference between two colors of equal brightness.

Chrominance: A colour term defining the hue and saturation of a colour. Does not refer to brightness.

(C) The colour portion of a video signal.

The part of the video signal corresponding to the color information.

This is the measure of color. In color television, the chrominance is technically the differeence between a given color and a standar color having the same brightness. The three chrominance primaries are red, green, and blue. This is why you might have heard the term RGB. These three primaries combine and form all colors that are seen on your Projection TV.

The colour part of a video signal

That portion of the video signal which contains the color information (hue and saturation). Video picture information contains two components: luminance (brightness and contrast) and chrominance (hue and saturation).

Color information whose form depends on the particular application.

The color component of a video signal, abbreviated C. Chrominance is combined with the black-and-white signal (luminance) in composite video connections, but kept apart in S-Video and component connections. For higher quality, the single chrominance signal can also be divided into B-Y and R-Y components in Y/PB/PR component connections, or into the primary colors of Red, Green and Blue for R/G/B component connections.

The color part of a video signal.

The perception of color.

In an image reproduction system, a separate signal that contains the color information. Black, white, and all shades of gray have no chrominance and contain only the luminance (brightness) portion of the signal. However, all colors have both chrominance and luminance. Chrominance is derived from the I and Q signals in the NTSC television system and the U and V signals in the PAL television system. See also luminance.

A signal that carries the colour information needed to produce a colour picture; (added to the luminance signal).

The color information in a composite video signal. Describes hue and saturation of a picture, but not the brightness. The signals R-Y and B-Y are examples of chrominance information.

This refers to the part of the video signal that contains the colour information. Mount Lens & CS Mount Lens There are two main types of lens used in CCTV cameras. The C mount lens has a flange back distance of 17.5mm. The CS mount lens has a flange back distance if 12.5mm. C mount lenses therefore have a longer focal distance. CS Mount became widely used, because it is more practical for many of today’s more compact cameras. Lenses are often supplied with a 5mm spacer ring (sometimes called a C ring) that allows a C mount lens to be used on a CS camera. Most modern cameras are CS.

The colour part of a TV signal that relates to the hue and saturation but not the brightness of the displayed image.

The colour element of a video signal. Known as C

A video signal carrying only the point-to-point color, both hue and saturation, of a video image and not its brightness; see luminance.

The property of a color that describes its saturation, intensity, or colorfulness, used in differentiating two colors of equal brightness and hue.

The color component (hue and saturation) of light, independent of luminance. Technically, chrominance refers to the linear component of video, as opposed to the transformed nonlinear chroma component.

A color term defining the hue and saturation of a color. Does not refer to brightness.

the color component of a composite signal or S-Video signal. Chrominance also refers to the color component of any image, as opposed to its grayscale value or luminance.

A color term defining the hue and saturation of a color. The other component, luminance can be thought of as the portion of the image absent of color or monochrome.

The color information contained in a video signal. This information is usually defined in terms of hue and saturation. The video signal is made up of chrominance (color) and luminance (brightness) information. The symbols are Cr (chrominance) and Cb (luminance).

The color portion of an image comprised of a mixture of hue and saturation or the combination of three primary colors, such as red, green, and blue.

The color component of a video signal that includes information about hue and saturation.

The color component of a modern television signal.

Chrominance (chroma for short), is the signal used in many video systems to carry the color information of the picture separately from the accompanying luma signal. Chrominance is usually represented as two color difference components: B'–Y' (blue – luma) and R'–Y' (red – luma). Both of these components have scale factors and offsets applied to them, which differ depending on the video signal scheme in question.
