Blooming
| CCTV glossary (глоссарий терминов по видеонаблюдению) |
- The defocusing of regions of the picture where the brightness is at an excessive level, due to enlargement of spot size and halation of the fluorescent screen of the cathode-ray picture tube. in a camera, sensor element saturation and excess which causes widening of the spatial representation of a spot light source.
- The defocusing of regions of a picture where brightness is excessive.
- A visual effect caused by overexposing a ccd to too much light, this digital overexposure can cause distortions of the subject and/or color.
- The spreading of strong highlights into surrounding areas of the image.
- The appearance of a bright or colored halo around brighter areas of digital image files. blooming is caused when a portion of the imaging sensor in a digital camera is exposed to too much light, causing signal “leaks” to the neighboring pixels. see chromatic aberration.
- An effect caused by overexposing a ccd or sensor to too much light. this can cause distortions of the subject and/or colour.

Bloom, 4. blow 1., английский
Выпотевание, русский
Вуаль; дефект из-за переэкспонирования светлых участков при сканировании;, русский
Просветление, русский
Покрытие, представляющее из себя несколько (часто более 10) слоев тонких пленок на поверхности оптических элементов. просветление снижает потери на поверхностное отражение, а также предотвращает образование бликов. так, например, на поверхности непросветленной линзы отражается 4-6% процентов света. в сложных оптических системах, потери могут достигать 50 и более процентов. в тоже время, оптика с качественным просветлением пропускает до 99,9% процента падающего на нее света.

Defocusing, английский
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.

- The attribute of color perception that expresses the amount of departure from the neutral gray of the same lightness. also referred to as chroma.
- Насыщенность
- Насыщенность (цвета). показатель, описывающий силу цвета и его уровень серого. мера чистоты цвета, определяющая количество содержащегося в нем серого. чем выше содержание серого, тем ниже насыщенность цвета
- In color, the degree to which a color is diluted with white light or is pure. the vividness of a color, described by such terms as bright, deep, pastel, pale, etc. saturation is directly related to the amplitude of the chrominance signal.
- Насыщение
- The degree to which a color is undiluted by white light. if a color is 100 percent saturated, it contains no white light. if a color has no saturation, it is a shade of gray.
- The degree of intensity of a hue. also, the result of hanging a hot light under an automatic sprinkler head.
- Saturation is the depth of the colors within a photographic image. photographs with deep levels of color are described as being heavily saturated. a photograph with lighter levels of saturation is described as having a muted color palette. a totally desaturated color photograph becomes monotone—or black and white.
- 1) in a communications system, the condition in which a component of the system has reached its maximum traffic handling capacity. 2) the point at which the output of a linear device, such as a linear amplifier, deviates significantly from being a linear function of the input when the input signal is increased. 3) the degree of the chroma or purity of a color.
- In color, a vividness, or intensity. some films have more inherent color saturation than others. saturation can be slightly increased by moderate film pushes, or by slight underexposure of certain slide films. saturation can be increased in color negative film by moderate overexposure.
- The degree to which a colour is undiluted by white light. if a colour is 100 percent saturated, it contains no white light. if a colour has no saturation, it is a shade of grey.
- A most important aspect in producing high quality leathers. full saturation of tanning, fat liquors and dyes are essential in the production of fine leathers. self-covered seat deck: in upholstered furniture, using cover fabric to cover area under loose cushions. also called self-covered deck. selvage: tightly woven edges that prevent fabric from fraying on the roll. the selvage must be cut away for many fabrics to drape smoothly. serpentine form: profile made up of convex curve flanked by two concave curves.
- N насыщение; запол- нение актантных позиций saussurean a соссюрианский
- Насыщение-отбора проб. обычно, особенно в сша, так называется прибор, в котором имеются таймер (регулятор выдержки времени), коллектор и 6 или более клапанов с проходным отверстием для подачи воздуха в различные устройства для забора проб через заданные интервалы времени. этот термин относится также к автоматическому устройству для ежечасных: замеров концентрации дыма. воздух пропускается при постоянной скорости через бумажный фильтр, на котором после этого остается темное пятно дымовых частиц. фильтровальная бумага (в виде свернутой в трубочку полоски шириной: 20—30 мм) проходит через зажим фильтра, закрепленный пружинами для обеспечения герметичности. в конце каждого-часа зажим открывается и полоска бумаги продвигается вперед на 40—50 мм, после чего зажим опять защелкивается. в результате на бумаге образуется ряд пятен, каждый час-по одному пятну. термин «последовательный пробоотборник» иногда применяется также для обозначения полуавтоматического прибора (см. semi-automatic apparatus).

- In color management, the purity of a color’s hue, moving from gray to the pure color. save (v)
- 1. the maximum intensity or purity of a color. if the color is as brilliant as possible, it is at saturation; if the color is subdued or grayed, it is dull, weak, and low in intensity. 2. the upper limit concentration of a solute in a solvent, i.e., no more solute can be dissolved at a fixed temperature and pressure.
- The intensity or purity of a hue; the color of the greatest purity are those in the spectrum. words used to describe saturation are vivid, dull, brilliant, dark, deep, light, medium, pale, and weak.

Representation, английский
- N репрезента- ция, представление knowledge ~ представление знаний internal ~ псхл. внутреннее представление mental ~ ментальная репрезентация
- A collateral statement of such facts not inserted on the policy of insurance, as may give the underwriters a just estimate of the risk of the adventure. (see warranty.)
- A representation is a set of conventions about how to describe a class of things. representation will generally consist of four parts: 1. a lexicon that determines which symbols are in it vocabulary; 2. a structural part that describes the constraints on the symbols; 3. a collection of methods or procedures that allow the symbols to be manipulated and queried; and 4. a semantics that specifies the meaning of the symbols and their relationships. re-ranking in handwriting and text recognition systems, the task of re-ranking allows the candidate interpretations developed by the recognizer to be ranked or scored according to the language model. see also: word n-gram re-ranking, word-tag model.
- If something stands in place of or is chosen to substitute for something else, the former is considered a representation of the latter. e.g., representation of constituencies in government, linguistic representation of an event (->symbol). the 66 belief that all knowledge is a representation of the properties of the real world is as unacceptable as the insistence that all descriptions or messages are about something else.
Overexposure, английский
- An image that appears too light. all the highlights and colors are totally lost and usually unrecoverable even by software.
- The result of recording too much light when taking a picture, which results in a lighter image. in digital imaging, overexposure can usually be corrected to a certain extent by the use of image-editing software, depending on the degree to which an image is overexposed. raw files offer more latitude than jpegs and tiffs for correcting overexposure.
- In exposure, when too much lighting strikes the film for a proper rendition of the scene. minor overexposure may cause a loss of details or texture in the scene highlights; severe overexposure will cause a serious deterioration of picture quality in color and black and white print film, and a complete loss of picture information with slide films.
- This is an image that appears much too bright. the highlights and colours are totally lost and usually unrecoverable even by top software. either the shutter speed was too long or the aperture was too wide.
- Слишком большая шумиха вокруг кого-либо; слишком частое упоминание в печати и т.п.
Highlights, английский
- A light spot, area, or streak on a painted surface.
- The bright areas of a subject or scene, often the result of gentle reflections of lights. strong reflections are called "kicks" or "hot spots." the size and intensity of highlights are determined in part by the hard or soft nature of the light and the subject texture. tip: diffusion enlarges and softens highlights. see: fall-off (light on a surface).
- The brightest parts of a scene that yield texture or image information. with slide film, it`s best to bias expose for the highlights, as overexposure of bright areas will yield a burnt-out look. a spectral highlight is pure light and will print as "paper" white.
- The ui label in messenger for the aspect of the social view that displays prioritized recent social activity of friends.
Surrounding, английский
Appearance, английский
- Manifestation of the nature of objects and materials through visual attributes such as size, shape, color, texture, glossiness, transparency, opacity, etc.
