Exempel på hur man kan använda LUMINANCE i en mening

• PAL video is composite video because luminance (luma, monochrome image) and chrominance (chroma, colour applied to the monochrome image) are transmitted together as one signal.
• SECAM video is composite video; the luminance (luma, monochrome image) and chrominance (chroma, color applied to the monochrome image) are transmitted together as one signal.
• The perception is not linear to luminance, and relies on the context of the viewing environment (for example, see White's illusion).
• Gamma correction or gamma is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems.
• The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance.
• The camera's shutter speed, the lens's aperture or f-stop, and the scene's luminance together determine the amount of light that reaches the film or sensor (the exposure).
• Exposure is measured in units of lux-seconds (symbol lxs), and can be computed from exposure value (EV) and scene luminance in a specified region.
• Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
• This system did not directly encode or transmit the RGB signals; instead it combined these colors into one overall brightness figure, the "luminance".
• Sky luminance distribution models have been recommended by the International Commission on Illumination (CIE) for the design of daylighting schemes.
• In photography, exposure value (EV) is a number that represents a combination of a camera's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance).
• Eads (2000) proposed a revised APEX in which luminance value was equal to EV for ISO 100 speed, but he did not use the term light value.
• The EDID data structure includes manufacturer name and serial number, product type, phosphor or filter type (as chromaticity data), timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.
• Human vision is unable to distinguish colors in conditions of very low luminance because the hue-sensitive photoreceptor cells on the retina are inactive when light levels are insufficient, in the range of visual perception referred to as scotopic vision.
• In 1975, Hitachi introduced a video disc system in which chrominance, luminance and sound information are encoded holographically.
• In the center of a so-called on-center receptive field, the individual photoreceptors excite the ganglion cell when they detect increased luminance; the photoreceptors in the surrounding area inhibit the ganglion cell.
• It is also used for setting a television monitor or receiver to reproduce NTSC chrominance and luminance information correctly.
• The company innovated a product that uses phosphor to convert blue laser light to produce a broad-spectrum, incoherent, high luminance white light source.
• While usually referring to luminance arising from artificial lighting, skyglow may also involve any scattered light seen at night, including natural ones like starlight, zodiacal light, and airglow.
• The pupillary light reflex (PLR) or photopupillary reflex is a reflex that controls the diameter of the pupil, in response to the intensity (luminance) of light that falls on the retinal ganglion cells of the retina in the back of the eye, thereby assisting in adaptation of vision to various levels of lightness/darkness.
