luminance
The degree of lightness or darkness in colors created by mixing lights The equivalent value in colors created by mixing pigments
The intensity of light in a color
a measure of light power refected or emitted from an object within a solid angle of one steradian per unit area area projected in a given direction The SI unit is the candela per square meter, which is sometimes called a nit See Brightness, Luminance, and Confusion from Information Display, March 1993 by Charles P Halsted at http: //www resuba com/wa3dsp/light/lumin html
the quality of being luminous
{i} brightness, luminosity
the luminous flux emitted in a given direction divided by the product of the projected area of the source element perpendicular to the direction and the solid angle containing that direction, i.e. luminous intensity divided by unit area; measured in stilbs or apostilbs
Perceived brightness, or grayscale level, of a color Luminance and chromaticity together fully define a perceived color
The light reflected or produced by a given area of a subject in a specific direction Measurable by a reflected-light (luminance) meter luminance meter See reflected-light meter
refers to the brightness information of the overall video signal Also see chrominance, component video, and S-video
The brightness information of a television picture It is also used to refer to the brightness component (Y signal) of a PAL, SECAM or NTSC television signal
Amplitude (strength) of the gray scale or black-and-white portion of the video signal
Although brightness is often used interchangably with luminance, we prefer to use the term "lightness " This concept deals with many of the same variables as value but using a different mathematical equation Check out our own definition of LUMINANCE/LIGHTNESS or more simply, think about the Color Wheel as colors having equal luminance Adding white will increase lightness and adding black will decrease it
The measure of the subject's "brightness" This is usually in terms of candles-per-square-foot
This term is used to describe the specific light which comes off the surface whether off a filament, light bulb, lens, louver, tabletop, etc Luminance varies with both the direction at which you view the surface and its gloss characteristics Luminance is measured in candela per square foot
Lightness The highest of the individual RGB values plus the lowest of the individual RGB values, divided by two; a component of a Hue-Saturation-Lightness image
the quotient of the luminous flux at an element of the surface surrounding the oint, and propagated in directions defined by an elementary cone containing the given direction, by the product of the solid angle of the cone and the area of the orthogonal projection of the element of the surface on a plane perpendicular to the given direction The luminous flux may be leaving, passing through, and/or arriving at the surface Formerly, photometric brightness
Luminance is a measure of luminous flux density per unit solid angle Luminance is typically expressed in candela per square meter (lumens per square meter per steradian), apostilbs (1/pi lumens per square meter per steradian) or foot-lamberts (1/pi lumens per square foot per steradian)
(1) (n ) The generic flux from a light-emitting or light-reflecting surface The subjective response to luminance is brightness (2) (n ) The specific ratio of color primaries that provides a match for the white point in a specified color space (3) (n ) The portion of a composite signal that carries brightness information See also chrominance
Density of luminous flux leaving a surface in a particular direction It is the quotient of the intensity of the source in the direction of measurement by the projected area of the source in that direction
