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.

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.

Brightness, luminance, английский
A measure of a surface`s or subject`s reflectivity in a given direction.
Brightness., английский
Image, английский
- Storage, translation and reproduction система хранения, передачи и воспроизведения записанных (на пленку) изображений
- Integrated mapping and geographic encoding system
- The likeness of an object produced by a lens or optical system.
- The optical reproduction of an object, produced by a lens or mirror. a typical positive lens converges rays to form a "real" image which can be photographed. a negative lens spreads rays to form a "virtual" image which can`t be projected.
- A representation of the functional pattern on a substrate
- Any representation of form or features, but esp. one of the entire figure of a person; a statue, effigy, bust, relief, intaglio, etc.
- A sensation, e.g. a smell, sight or taste, which is remembered clearly
- The illusory sound field located between two stereo speakers.
- Visual representation of a test object or scene.
- Visual representation of an object or scene.
- Reproduction of an object produced by light rays. an image forming optical system gathers a beam of light diverging from an object point and transforms it into a beam that converges toward another point, thus producing an image.
