Contrast
|
- The difference in intensity between the darkest and the brightest parts of an image.
- The level of variation between light and dark areas in an image.
- Контраст
- The range of light to dark values in a picture or the ratio between the maximum and minimum brightness values.
- A common term used in reference to the video picture dynamic range, i.e., the
- Контраст; контрастный
- A measure of rate of change of brightness in an image.
- A common term used in reference to the video picture dynamic range, i.e., the difference between the darkest and the brightest parts of an image.
- The apparent difference in perceived brightness between two areas within the field of view. = (bmax - bmin)/bmax bmax = maximum brightness bmin = minimum brightness
- The difference between one tone and another or between the darkest and lightest parts of a scene or processed film. high contrast involves not only an extreme brightness ratio but also few gray tones. low contrast has an expanded range of intermediate tones with limited pure blacks and whites. tip: what is too contrasty for one medium or emulsion may not be so for another. see: brightness ratio; and fall-off (on a surface).
- The relationship between the lightest and darkest areas in a scene and/or photograph. a small difference means low contrast; a great difference high contrast. high contrast scenes usually cause the most exposure problems; however, their difficulty can mean they hold the potential for more expression. though contrast is often linked with scene brightness, there can be low contrast in a bright scene and high contrast in dim light. contrast can also describe attributes of color, composition, and inherent qualities of film.
- The measure of rate of change of brightness in an image.

- The degree of difference between light and dark extremes of color on a monitor, device screen, or printed output, or between the darkest and lightest areas in a photo. the greater the difference, the higher the contrast.
- An indication of the difference between the thicker and thinner parts of characters in a typeface.
- Visible differences between parts of a microscopic specimen
- Comparison of two or more colors in such a way that enables them to be differentiated. color theorist johannes itten [learn more about his theories here and here] was one of the first to define the contrasting properties of color. itten noted seven types of color contrast:
- (1) difference in color or brightness between a test indication and its background or surroundings. (2) in film radiologic testing, the difference in film blackening or density observed from one area to another and resulting from various radiation intensities transmitted by the object. contrast, subject: ratio of radiation intensities transmitted by selected portions of object being radiographed.
- (1) разница в цвете или яркости между индикатором испытания и его фоном или окружением. (2) при радиологических испытаниях пленки - разница в почернении или плотности пленки, наблюдаемая на разных участках и возникающая в результате различной интенсивности излучения, передаваемого объектом. контраст, предмет: соотношение интенсивностей излучения, передаваемого выбранными частями рентгенографируемого объекта.
- Difference in color or brightness between a test indication and background.
- Difference between the amount of light reflected or transmitted by an object and by the background in the field of view. 306 visual testing
- Difference in visibility (brightness, color or temperature) between an indication and the surrounding surface.1
- (1) difference in color or brightness between a test indication and background. (2) difference between the amount of light reflected or transmitted by an object and by the background in the field of view.
- Difference in color or brightness between indication and background.

Контрастность, русский
Отношение максимальной освещенности проекционного экрана или яркости плазменной панели к минимальной при проецировании белого и черного поля соответственно.
Контраст, русский
- Разница между самой светлой и самой темной областями изображения.
- Контраст , противоположный
- Резко выраженная противоположность.
- , отношение разности яркостей объекта и фона к их сумме. пороговый контраст - минимальный контраст, воспринимаемый глазом.
- (франц . contraste), резко выраженная противоположность.
- В архитектуре - средство архитектурной композиции, заключающееся в сочетании элементов архитектурной формы, резко различающихся по внешним характеристикам
- 1) контраст объекта съемки представляет собой отношение яркостей самой светлой и самой темной частей объекта 2) контраст фотографического изображения — тональная характеристика изображения, характеризующая различие в светлоте его наиболее ярких и наиболее темных участков 3) контраст освещения — величина характеризующая различие яркостей различных участков объекта

Difference, английский
- Disagreement, inequity, contrast, dissimilarity, incompatibility
- Разница; разность
- An important army term, meaning firstly the sum to be paid by officers when exchanging from the half to full pay; and, secondly, the price or difference in value of the several commissions.
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

Contrast control, английский
- The control on a monitor used to change the contrast by varying the amplitude of the video signal.
- Регулировка контрастности contrast-equalizing tool инструмент "автоматическое выравнивание контрастности"
Conduit, английский
- Plastic or metallic pipe, which is used to conceal and protect cables and wiring.
- Проводник; труба, трубопровод; кабелепровод
- A pipe made of metal, plastic, or clay used for the installation of communications or power cables between two or more locations
- Труба
- Metaphor

- Pipe or casing placed in a borehole. see casing, drive pipe.
- A tube or trough for receiving and protecting electric and telephone wires.
- A pipe or elongated box used to house and protect electrical cables.
- Pipe or liner used as a passage for other pipes or wires.
