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

Brightness amplifier (rt), английский
Brightness control, английский
- Control, which increases or decreases the illumination of phosphors on a monitor screen to vary the brightness.

Brightness converters, английский
Optically pumped devices where the generated optical output has a higher brightness than the optical pump source

Brightness meter, английский
A common expression for a luminance meter.
Brightness range, английский
Brightness range of object, английский
Brightness ratio, contrast ratio, английский
The all-too-often awful truth about a subject or scene that has inappropriate or excessive contrast. meter reading procedure: take two reflected-light readings: 1) the lightest significant area of the subject or scene and 2) the darkest. divide 1) by 2). each medium or method of reproduction has different brightness ratio limits. movie theaters can project a maximum of about 125:1 (7 stops plus); modern, well-adjusted video cameras 30 or, some pros suggest, 40:1. also see: lighting ratio and contrast.

Drop, английский
- (petite) chute en marche
- A small quantity of liquid that falls or is produced in a more or less spherical mass; a liquid globule
- Точка подключения оборудования пользователя к кабельной системе
- Сбрасывание (груза)
- A cable that delivers service to an individual customer.
- 1. a small quantity of liquid 2. a sudden reduction or fall in the quantity of something a drop in pressure plural
- Спустить (петлю)
- [1] to move gently with tide or current. [2] the depth of a square-sail measured amidships.
- The small downward descent of the upper section of a drill rod, casing, or pipe into a lower like section when the threads of the box- and pin-threaded parts match, so that upper and lower sections may be screwed together without cross-threading.
- The sudden descent of a bit that occurs when a bit encounters a cavity or cuts through a hard rock and enters a very soft rock, example: a driller may say "the bit hit a cavity and dropped 6 inches."
- To lose equipment in a borehole. 4. to lower drill-string equipment into a borehole.
