Luminance, английский
- Brightness. in cctv refers to the part of the video signal that contains information about the scene brightness.
- Яркость. составляющая изображения, определяющая его относительную яркость в каждой точке экрана монитора
- This refers to the part of a video signal that carries the monochrome information. i.e. brightness information.
- Luminous intensity (photometric brightness) of any surface in a given direction per unit of projected area of the surface as viewed from that direction, measured in foot lamberts (fl).
- Luminous intensity (photometric brightness) of any surface in a given direction per unit of projected area of the surface as viewed from that direction, measured in footlamberts (fl).
- Refers to the video signal information about the scene brightness. the measurable,
- The part of a composite video signal that expresses brightness. also called y. separately transmitted in y/c (s-video).
- 1. luminous flux emitted, rejected, or transmitted per unit of solid angle per projected area of the source. 2. the photometric equivalent of brightness. 3. the brightness part of a television picture.
- Refers to the video signal information about the scene brightness. the measurable, luminous intensity of a video signal. differentiated from brightness in that the latter is nonmeasurable and sensory. the color video picture information contains two components, luminance (brightness and contrast) and chrominance (hue and saturation). the photometric quantity of light radiation.
- The luminous intensity of any surface in a given direction per unit of projected area of the surface, as viewed from that direction; a directional property of luminous radiation.
- The perceived brightness component of a given color, as opposed to its hue or its saturation.
- Яркость. относится к содержащейся в видеосигнале информации об освещенности объекта. фотометрическая единица измерения светового излучения.
- Ratio of a surface’s luminous intensity in a given direction to a unit of projected area. measured in candela per square meter.
- Photometric brightness of a light source defined by the density of its luminous intensity, measured as luminous flux per unit solid angle per unit area in a given direction. reported in candela per square meter (cd·m–2).
- Photometric brightness of a light source defined by the density of its luminous intensity, measured as luminous flux per unit solid angle per unit area in a given direction. reported in candela per square meter (cd/m2). compare illuminance. 504 glossary l-m luminous efficacy; luminous efficiency: ratio of the total luminous flux of a light source to the total radiant flux or to the power input.
- Photometric brightness of a light source as defined by the density of its luminous intensity. luminance is a measure of the luminous flux per unit solid angle per unit area in a given direction and is reported in candela per square meter (cd·m–2).

Luminance factor, английский
- The ratio of the luminance of a surface or medium under specified conditions of incidence, observation, and light source to the luminance of a lossless, perfectly diffusing surface or medium under the same conditions. luminance meter, brightness meter a visual instrument or a photoelectric instrument used to measure luminance.

Ratio attribute, английский
A ratio-valued attribute takes on values for which the absolute value is meaningful, and has a true zero, such as a weight or count. ratios of these numbers refer to ratios of physical quantities. translation or scaling of these numbers would change their meaning. a ratio attribute can be either continuous valued or discrete valued (e.g., a count). see also: interval attribute, machine learning, nominal attribute (type), ordinal attribute.
Ratio calendar combination, английский
A strategy consisting of a simultaneous position of a ratio calendar spread using "calls" and a similar position using puts, where the striking price of the "calls" is greater that the striking price of the "puts".
