chrominance

Next, the chrominance is demodulated to produce color difference video data.

Each pixel has two values, which are luminance and chrominance.

Saturation is directly related to the amplitude of the chrominance signal.

Detects the absence of chrominance information in a color encoder input.

Following these eight cycles, a phase shift in the chrominance signal indicates the color to display.

A black-and-white TV filters out and ignores the chrominance signal.

The compromise can improve text appearance when luminance detail is more important than chrominance.

The chrominance components can be, but do not necessarily have to be, down-scaled in resolution.

I and Q represent the chrominance information.

In effect, the remaining chrominance values represent the nearby values that are deleted.

A color image has three values per pixel and they measure the intensity and chrominance of light.

The S-Video chrominance signals with these encodings are decidedly different.

Thinning works because the eye better resolves brightness details than chrominance details.

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

With more backlight, a higher chrominance is available and a color image display is seen.

This system stores a luminance value with two chrominance values, corresponding approximately to the amounts of blue and red in the color.

One, known as luminance, governs the brightness of each image point; the other, called chrominance, determines the hue.

Analogue colour video signals comprise two components: chrominance and luminance.

Chrominance does not refer to brightness.

Another common practice to reduce the data rate is to "thin out" or subsample the two chrominance planes.

The paler color has higher luminance, and lower chrominance (or color saturation).

Finally the luminance and chrominance components are scaled to 8-bit values by the following equations:

The transmission of a signal wave which represents the brightness values in the picture, but not the color (chrominance) values.

In many cases when this connection is made, the result will be a predominantly black-and-white picture, with most of the colour (chrominance signal) washed out.

Each picture element (a pixel) is then represented by one luma number and two chrominance numbers.
