- 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.

- 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).

Яркость, русский
- Воспринимаемая интенсивность света. это восприятие (с точки зрения наблюдателя-человека) нелинейно.
- Характеристика удельной интенсивности свечения излучающей или отражающей поверхности. яркость измеряется силой света, излучаемого единицей поверхности. единицей яркости является кандела / кв.м. в последнее время получило распространение употребление терми
- , характеристика светящихся тел, равная отношению силы света в каком-либо направлении к площади проекции светящейся поверхности на плоскость, перпендикулярную этому направлению. в системе си измеряется в канделах на м2.
- Величина, характеризующая интенсивность свечения источника света или отражающей поверхности,
- Поверхностно-пространственная плотность светового потока
- Яркость - отношение силы света источника в данном направлении к площади светящейся поверхности, видимой в том же направлении.
- Яркостью называется величина интенсивности света, отраженного от поверхности. это мера воспринимаемой яркости или затемности поверхности.
- Это величина потока, излучаемого единицей площади в единицу телесного угла в данном направлении.
- Интенсивность света, отраженного от поверхности. это мера воспринимаемой яркости или затемненности поверхности

Brightness, английский
- Term for the intensity of illumination of a reproduced video picture.
- The attribute of visual perception in accordance with which an area appears to emit or reflect more or less light (this attribute of color is used in the color model hsb - hue, saturation, brightness). see lightness.
- A term to indicate the relative amount of light intensity available. brighter is more light, dimmer is less light. in an infrared system, the brightness control may affect actual image intensity or it may change the temperature range displayed. either eff
- The attribute of visual perception in accordance with which an area appear to emit more of less light. (luminance is the recommended name for the photo-electric quantity which has also been called brightness.)
- In ntsc and pal video signals, the brightness information at any particular instant in
- Яркость
- The value of a pixel in an electronic image, representing its lightness value from black to white. usually defined as brightness levels ranging in value from 0 (black) to 255 (white).
- In ntsc and pal video signals, the brightness information at any particular instant in a picture is conveyed by the corresponding instantaneous dc level of active video. control is an adjustment of setup (black level, black reference).
- Is strictly defined as an attribute of a visual sensation according to which an area appears to emit more or less light. we sometimes misuse the term brightness in this catalog instead of the more correct “luminance.” luminance, used for sources, is the luminous flux in an elemental beam from a given point per unit area per solid angle in the specified direction.
- The visual sensation of the luminous intensity of a light source. the brightness of a laser beam is most closely associated with the radiometric concept of radiance.
- A term mostly used in a qualitative way, related to the output power and beam quality of a laser; quantitatively
- The luminance of objects. the brightness of any area of the subject is dependent on how much light falls on it and how reflective it is. brightness range is the relationship we perceive between the light and dark subjects in a scene. brightness contrast is a judgment of the relative measure of that range, such as high, low, or normal. brightness values are sometimes referred to as ev (exposure values), a combination of aperture and shutter speed. brightness values in the scene are translated to tonal values on film.
- Value of a pixel in a digital image giving its value of lightness from black to white, with o being black and 255 being white.
- That attribute of visual perception in accordance with which a surface appears to emit more light or less light. now called luminance.
- The amount of light that is emitted by a computer monitor or picture displayed on the monitor.
- Яркость. для видеосигналов систем ntsc и pal
