- A color term defining the hue and saturation of a color. does not refer to brightness.
- The color information of a color video signal.
- Color part of the composite video signal. also called c. separately transmitted in y/c (s-video). it is the combination of the two color difference signals (u or r-y) and (v or b-y) modulated on to a subcarrier. see also yuv.
- The color information of a color video signal. -to-luminance intermodulatlon (crosstalk, cross-modulation)an undesirable change in luminance amplitude caused by superimposition of some chrominance information on the luminance signal. appears in a tv picture as unwarranted brightness variations caused by changes in color saturation levels.

Цветность, русский
- Количество красок, в которые запечатывается издание. обычно обозначается при помощи цифр: 4+0, 1+1 и т.д. первая цифра - количество красок на лицевой стороне, вторая - на обороте. такое обозначение наиболее часто встречается в прайс-листах.
- Окраска воды, вызванная содержанием органических или минеральных примесей, не поддающихся удалению с помощью механической очистки. цветность природной воды часто бывает вызвана наличием в ней гуминовых и фульвовых кислот. цветность в хозяйственно-питьевой воде не должна превышать 20 градусов. хорошо понижается обратным осмосом. для снижения цветности также могут применяться сорбционный метод или окисление с последующим фильтрованием.

Вектор, русский
- (от лат . vector - несущий), отрезок определенной длины и направления. обычно вектор обозначается буквой a или (первая буква - начало, вторая - конец отрезка); абсолютная величина (длина) вектора записывается |a| либо . два вектора равны лишь в том случае, если у них одинаковы длины и совпадают направления (т. е. они параллельны и одинаково ориентированы). с изменением ориентации меняется знак вектора. векторы изображают т. н. векторные величины: силу, скорость, ускорение и т. д. действия над вектором изучают в векторном исчислении.

- 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.

- 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.
- Condition in which high amplitude signals on a display screen do not increase with increased gain and appear flattened.
- Relative or comparative color characteristic resulting from a hue’s dilution with white light.

- 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.
