Chrominance in a sentence

Designers chose to make the chrominance subcarrier frequency an n + 0.5 multiple of the line frequency to minimize interference between the luminance signal and the chrominance signal.

A color television system is identical except that an additional signal known as chrominance controls the color of the spot.

A monochrome signal is identical to a color one, with the exception that the elements shown in color in the diagram (the color burst, and the chrominance signal) are not present.

Because the human eye is less sensitive to details in color than brightness, the luminance data for all pixels is maintained, while the chrominance data is averaged for a number of pixels in a block and that same value is used for all of them.

But a spectrum analyzer instrument shows that, for transmitted chrominance, the frequency component at the subcarrier frequency is actually zero energy, verifying that the subcarrier was indeed removed before transmission.

Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture, separately from the accompanying luma signal (or Y for short).

For example, the chrominance on odd lines would be switched directly through to the decoder and also be stored in the delay line.

Fortunately, the human visual system is similar in design: it perceives changes in luminance at a higher resolution than changes in chrominance, so this asymmetry has minimal visual impact.

In a Bayer filter arrangement, green is given twice as many detectors as red and blue (ratio 1:2:1) in order to achieve higher luminance resolution than chrominance resolution.

Like most other types of subpixel rendering, ClearType involves a compromise, sacrificing one aspect of image quality (color or chrominance detail) for another (light and dark or luminance detail).

Luminance only, Chrominance only, and full color image.

Most modes use an RGB color model ; some modes are black-and-white, with only one channel being sent; other modes use a YC color model, which consists of luminance (Y) and chrominance (R–Y and B–Y).

Separating RGB color signals into luma and chrominance allows the bandwidth of each to be determined separately.

Similarly, the terms luminance and chrominance are often used instead of the (more accurate) terms luma and chroma.

The color information is called chrominance or C for short, while the black-and-white information is called the luminance or Y for short.

The resulting subcarrier sidebands is also known as "chroma" or "chrominance".

This frequency was chosen to minimize the chrominance beat interference pattern that would be visible in areas of high color saturation in the transmitted picture.

This takes advantage of the fact that the human eye perceives spatial changes of brightness more sharply than those of color, by averaging or dropping some of the chrominance information in the image.
