Examples of luminance
luminance
The luster might lose a little more luminance if the kitchen is too enthusiastic.

Essentially what they're doing is including a hard luminance-detecting element.

For the video, luminance is simply frequency modulated and written to the Y track.
From the en.wikipedia.org
Luminance is used in the video industry to characterize the brightness of displays.
From the en.wikipedia.org
The hindrances to 3D are sharpness and luminance, both of which will improve quickly.
From the latimes.com
Video8-XR and Hi8-XR offered a modest 10% improvement in luminance detail.
From the en.wikipedia.org
This provides separate lines for the luminance, red shift, and blue shift.
From the en.wikipedia.org
The formal relationship of EV to luminance or illuminance has limitations.
From the en.wikipedia.org
Colour represents phase and luminance represents normalized amplitude.

- Luminosity: the quality of being luminous; emitting or reflecting light; "its luminosity is measured relative to that of our sun"
- Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. ...
- Relative luminance follows the photometric definition of luminance, but with the values normalized to 1 or 100 for a reference white. ...
- In video, luma represents the brightness in an image (the "black and white" or achromatic portion of the image). Luma is typically paired with chroma. Luma represents the achromatic image without any color, while the chroma components represent the color information. ...
- The quality of being luminous; the luminous flux emitted in a given direction divided by the product of the projected area of the source element perpendicular to the direction and the solid angle containing that direction, i.e. luminous intensity divided by unit area; measured in stilbs or apostilbs
- The black and white (Y) portion of a composite, Y/C, or Y/Pb/Pr video signal. The luminance channel carries the detail of a video signal. The color channel is laid on top of the luminance signal when creating a picture. ...
- Perceived brightness, or grayscale level, of a color. Luminance and chromaticity together fully define a perceived color.
- The overall brightness of a computer screen.
- The relative brightness values of a particular object in a scene.
