Luminance in a sentence

The blinding effect is caused in large part by reduced contrast due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance similar to the background luminance.

But the biggest benefit when we compare them to LED TVs is that each individual pixel receives its own luminance and power (as opposed to LED TVs, which have persistent pixels that require an external source of light to see).

We've put the G4 through several picture tests and were absolutely blown away by its peak luminance, breathtaking colors, and next-level HDR performance.

HDR simply means a larger difference in luminance between the darkest area of an image and the brightest area.

The hue control will adjust the color’s shade while saturation adjusts the amount of that color, and lightness (also called luminance) changes how light or dark the color is.

Applications Magnetic tape storage FM is also used at intermediate frequencies by analog VCR systems (including VHS ) to record the luminance (black and white) portions of the video signal.

As it passes each point the intensity of the beam is varied, varying the luminance of that point.

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.

BTR-12, no. 1, pp. 23 32. introducing both hue and luminance errors for highly saturated colors.

But as all of us who have toyed with magnets or charged balls well know, their forces (or any other forces for that matter), even when set in motion produce no luminance at all.

Cross colour refers to when any high frequency luminance content of the picture, close to the TV systems colour sub-carrier frequency, is interpreted by the analogue receiver's decoder as colour information.

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.

For real, passive, optical systems, the output luminance is at most equal to the input.

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.

Green not only has a higher luminance value than blue, but also in early digital formats, the green channel was sampled twice as often as the blue, making it easier to work with.

However, the luminance is not constant across the disk of the Sun ( limb darkening ).

If the man pumps the magnet up and down, then, according to Maxwell 's theory of artificial luminance (AL), it will initiate a spreading circle of electromagnetic waves and will thus be luminous.

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.

In a monochrome receiver the luminance signal is amplified to drive the control grid in the electron gun of the CRT.

Instead, the RGB signals are converted into YUV form, where the Y signal represents the lightness and darkness (luminance) of the colors in the image.
