luminance's Usage Examples:

brightness is the perception elicited by the luminance of a visual target.

It is not necessarily proportional to luminance.

luminance (technically relative luminance) as the original colour image (according to its colourspace).

In addition to the same (relative) luminance,.

in video engineering and relative luminance as used in color science (i.

Relative luminance is formed as a weighted sum of linear.

Contrast is the difference in luminance or colour that makes an object (or its representation in an image or display) distinguishable.

The candela per square metre (symbol: cd/m2) is the derived SI unit of luminance.

chrominance (color) components; luminance is denoted by Y and luma by Y′ – the prime symbols (') denote gamma correction, with "luminance" meaning physical linear-space.

This page lists examples of luminances, measured in candelas per square metre and grouped by order of magnitude.

combinations that yield the same exposure have the same EV (for any fixed scene luminance).

an objective specification of the quality of a color regardless of its luminance.

It results from intermodulation or crosstalk between chrominance and luminance components of the signal, which are imperfectly multiplexed in the frequency.

A foot-lambert or footlambert (fL, sometimes fl or ft-L) is a unit of luminance in United States customary units and some other unit systems.

achromatic lightness quantity (dependent solely on the perceptually achromatic luminance Y, but not the mixed-chromatic components X or Z, of the CIE XYZ color.

Relative luminance follows the photometric definition of luminance, but with the values normalized to 1 or 100 for a reference white.

Y′ (with prime) is distinguished from Y, which is luminance, meaning that light intensity is nonlinearly encoded based on gamma corrected.

correction or gamma is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems.

unit of luminance named for Johann Heinrich Lambert (1728–1777), a Swiss mathematician, physicist and astronomer.

A related unit of luminance, the foot-lambert.

refers to a motion illusion generated by the presentation of a sawtooth luminance grating in the visual periphery.

Glare is caused by a significant ratio of luminance between the task (that which is being looked at) and the glare source.

where Vin is the luminance of the original pixel and Vout is the luminance of the filtered pixel.

This function will map the luminance Vin in the domain.
