brightness 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. the location of a visual perception along a continuum from black to white
  2. intelligence as manifested in being quick and witty
  3. luminosity: the quality of being luminous; emitting or reflecting light; "its luminosity is measured relative to that of our sun"
  4. (brightly) brilliantly: with brightness; "the stars shone brilliantly"; "the windows glowed jewel bright"
  5. Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. This is a subjective attribute/property of an object being observed.
  6. The Brightness is the third album by American folksinger Anais Mitchell, released February 13, 2007 on Righteous Babe Records. It was recorded at The Bristmill in Bristol, Vermont and produced by Michael Chorney.
  7. (Brighter (Paramore Song)) All We Know Is Falling is the debut album by American alternative rock band Paramore. The album reached #8 on the UK Rock Chart. In the USA, it reached #30 on the Billboard's Heatseekers Chart but failed to chart on the Billboard 200.
  8. (brightly) In a bright manner
  9. For video, the overall light level of the entire image. A brightness control makes an image brighter; however, when it is combined with a contrast, or white level control, the brightness control is best used to define the black level of the image (see Black Level). ...
  10. The brilliance or reflectance of paper.
  11. The attribute of visual perception in accordance with which an area appears to emit more of less light. (Luminance is the recommended name for the photo-electric quantity which has also been called brightness.)
  12. In color, the difference in range from white when compared to dark tones and colors. Could also be considered to be contrast. In photography, brightness is dependent upon correct exposure. Overexposures will be very bright but will have lost highlight density details. ...
  13. [of fleece]: the quality of alpaca fiber that reflects light
  14. Usually refers to the amount or intensity of video light produced on a screen without regard to colour. Sometimes called 'black level'.
  15. Characteristic of paper referring to how much light it reflects.
  16. Brightness is measured as the percentage of light in a narrow spectral range reflected from the surface of a sheet of paper. It is not necessarily related to color or whiteness. A paper with a brightness of 98 is an extremely bright sheet with almost all light being reflected back to the viewer. ...
  17. The dimension of color that is referred to an achromatic scale, ranging from black to white, also called lightness or luminous reflectance. Because of confusion with saturation, the use of this term should be discouraged.
  18. The light level intensity of a computer monitor, adjusted in unison with contrast to effect the quality of the viewable image.
  19. the amount of light being reflected off a scanned object.
  20. Brightness can refer to any of several technical terms used in lighting and is, therefore, ambiguous (See LUMINANCE ).
  21. A measure of the amount of light reflected by a paper at a wavelength of 457 +/- 5 mm. Printers, publishers, sellers refer to brightness which may be approximately by various photometers such as Photovolt, Elrepho, GE Brightness, Hunter Lab. They all give somewhat different readings for brightness.
  22. The perceived intensity level of light in a visual scene.
  23. The brightness of a projection system can be precisely measured with a light meter. For example, a typical movie theater is setup to deliver 16 foot-Lamberts. The higher the foot-Lamberts, the brighter the image. ...
  24. Brightness refers to the lightness or darkness of the image. Brightness is one of the three dimensions, with saturation and hue, in color space settings. If the brightness is set to 0% then the resulting image will be completely black. ...
  25. The light reflecting property of a paper. The more light it reflects the higher its brightness. A bright sheet offers the best print quality and appearance.
