Chromatic aberration, английский
- Optical term, which refers to the distortion of an image as a result of a scattered focal point caused by a defect in a lens. a combination of lens can be used to correct this effect.
- Chromatic aberration. failure of a lens to focus all colours at the same point. the aberrations can be along the optical axis (longitudinal ca, or loca) or off-axis (lateral or transverse ca, tca).
- An optical defect of a lens which causes different colors or wave lengths of light to be focused at different distances from the lens. it is seen as color fringes or halos along edges and around every point in the image.
- Also known as the purple fringe effect. it is common in two megapixel and higher resolution digital cameras (especially those with long telephoto zoom lenses) when a dark area is surrounded by a highlight. along the edge between dark and light you will see a line or two of purple or violet colored pixels that shouldn`t be there.
- Also known as color fringing, chromatic aberration occurs when the collective color wavelengths of an image fail to focus on a common plane. the results of chromatic aberration are most noticeable around the edges of high-contrast images, especially toward the edges of the frame. chromatic aberration is most common on less expensive lenses, although even the best optics can occasionally display lower levels of chromatic aberration, under certain conditions.
- In terms of lens optics it is the failure of the lens to focus all colours (rgb) at the same point. it shows up as colour fringes in areas of the image where dark meet light (think edge of a building against the sky). it is more common in wide angle lenses, and those of inferior optics (kit lenses). it is correctable, to some degree, using photoshop, lightroom or software of your choice.
- Also known as purple fringing. it is fairly common in 2mp digital cameras and above, especially if they have long telephoto lenses. you can see it when a dark area is surrounded by a highlight. in between the dark and light, you may see a band of purple pixels that shouldn’t be there. there are ways of removing this which i have covered in the photoshop section.
- When a lens causes white light to be broken into various component colors with each focus at a different distance from the lens, commonly producing color fringe around a viewed image.
Television, английский
- Телевидение; телевизионный
- The electronic transmission of pictures and sounds.
- Телевидение
- An electronic system of transmitting transient images of fixed or moving objects together with sound through space by an apparatus that converts light and sound into electrical waves and reconverts them into visible light rays and audible sound.
Saturation, английский
- The condition when the partial pressure of water vapour in the atmosphere is at its maximum level for the existing temperature and pressure. for example, at saturation an equilibrium exists between water vapour and liquid water and there is no net evaporation or condensation.
- 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).
- Overload of a magnetic tape. the saturation point is the point at which an increase in magnetizing force does not cause a corresponding increase in magnetization of the tape oxide particles.
- 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.
- (1) in nondestructive testing, signal amplitude at or above sensor’s maximum capability. (2) relative or comparative color characteristic resulting from a hue’s dilution with white light.
- Magnetic saturation.
- Condition in which high amplitude signals on a display screen do not increase with increased gain and appear flattened.7
