Illuminance, английский
- The amount of light, which falls onto a given surface area. measured in lux.
- The light density, or luminous flux per unit area, incident on a surface.
- The density of luminous power, also called “illumination.” one lumen of luminous flux, uniformly incident on 1 square foot of area, produces an illuminance of 1 footcandle; in si units, one lumen of luminous flux, uniformly incident on 1 square meter of area, produces an illuminance of 1 lux.
- Освещ
- Intensity of radiant energy (density of luminous flux) on a surface, in the visible light spectrum. illuminance is measured in lux.
- Intensity of visible light per unit area (density of luminous flux) on a surface. illuminance is measured in lumens per square meter (lm/m2) or lux. compare luminance.
- Intensity of radiant energy in the visible light spectrum. illuminance is measured in footcandles or lux.
Horizontal resolution, английский
- The number of vertical lines that can be resolved in a picture.
- Chrominance and luminance resolution (detail) expressed horizontally
- Number of equally spaced vertical black-to-white or white-to-black transitions that the camera is able to reproduce, divided by the aspect ratio (usually 43) to make a comparison between horizontal and vertical resolution easier. usually expressed as tv lines per picture height. indicates the amount of horizontal details that can be perceived. horizontal resolution is limited by the number of pixels in one line and by the type of color filter used, if any.
- The maximum number of black and white vertical lines that can be resolved within a horizontal expanse of raster equal to one picture height. ntsc television pictures normally have 300 lines of resolution or less.
- Chrominance and luminance resolution (detail) expressed horizontally across a picture tube. this is usually expressed as a number of black to white transitions or lines that can be differentiated. limited by the bandwidth of the video signal or equipment.
- Разрешающая способность по горизонтали. хроматическая и яркостная разрешающая способность (детализация), оцениваемая по горизонтали изображения на экране кинескопа. обычно выражается в виде числа переходов от черного к белому или в виде числа различимых линий. ограничена полосой частот видеосигнала или полосой пропускания оборудования.
