ICC (International Color Consorltium) International Color Federation: International Committee for the Development of Color Data Standards, see "Data Maps".
Illuminance: The degree to which a light source illuminates an object.
Just-perceptibledifference: A color difference that cannot be resolved by human vision.
Kellfactorkell parameter: Calculates the vertical scan line quality parameter of the playback screen. In general, the secondary parameter has a value of 0.7.
Linearization: A special calibration that adjusts the linear relationship between the input and output after the output has been adjusted. For example, the halftone dot value output after linearizing the image output machine is within a certain tolerance range of its input.
Luminanceadaptation bright adaptation: When the light intensity of the illumination light changes, the visual function of the human eye will automatically adapt to the adjustment, and the information can still be obtained normally.
Luminance: The intensity of the illuminator.
Luminous body: An object that emits light by itself, such as the sun, fluorescent lamps, flames, electric lights, etc.
Luminous intensity point: the intensity of the light source (I), I = dΦ / dw.
Metamerism: An item with the same tristimulus value and different spectral distribution.
Munsellcolorsystem Munsell color system.
Neutralcolor Neutral: Neutral gray without color.
Non-luminous body: A device that does not emit light by itself and receives light from the illuminator to produce a glossy object.
Opacity opaque: An object with zero light penetration.
Photopicvision: In the brighter conditions, only the cone acts. This visual state is called bright vision.
Preferencecolor preference color: similar to favoritecolor (like color); but more special emphasis on certain ethnic groups, groups, individuals with special preferences.
ProfileorICCProfile data map or International Color Consortium data map: Developed by the International Color Consortium and published in 1995, the data graph is a standard file format that transmits the color output of a system or device in response to known inputs. Describe a device such as a characterization that supports applications and operating systems in this format.
Quartzhalogenlamp quartz halogen lamp: the most commonly used light source for color measurement and spectrometer measurement, such as continuous spectrum light source and high color rendering light source.
Rod rod body cells: located in the human eye, only play in the darker conditions (brightness is less than 0.01nits), suitable for low-light vision, it has high sensitivity, low resolution, no color resolution, its sensitivity The range is from 400 to 600 nm.
Saturation: The purity of a color. The more the spectrum penetrates into other light components, the less saturated it is.
Scotopicvision Dark Vision: In the darker conditions only the stalk acts. This visual state is called dark vision.
Sensitivity: The degree of brightness that is felt when you see light.
Spectraldistribution: The fraction of energy emitted by a source for each spectral interval as a percentage of total energy.
Spectrophotometer: A device that measures the amount of reflected or transmitted light at regular intervals throughout the visible spectrum. Spectrophotometric data can be used to calculate concentration and chromaticity variables.
Spectrum spectrum: If the emitted light is described by three main light waves: red, green and blue, then when combined with these three different proportions of the main light wave, a complete spectrum containing all colors will be produced.
Spetraltristimulusvalues spectral tristimulus values: tristimulus values, tristimulus values (X, Y, Z) are the three basic values of the CIE color system, consisting of three basic color elements such as light source, object and receiver.
Tristimulusvalue: The three color stimuli that simulate the human eye and can be matched to the color seen by standard observers under the CIE standard illuminator.
UCR (UnderColorRemoval) background color removal: This technology is applied to printing, which can effectively remove the color overlap of the shadow part and adjust the midtone to balance the gray shade.
Value brightness: V for short is the name that distinguishes the degree of shading.
Visualangle perspective: The angle at which the ends of the visual target form at the pupil.
Visualfield: The area that can be seen when both eyes (still).
Visualspectrum visible spectrum: visible light with a wavelength of 380nm~780nm, in this range, the naked eye will cause a reaction and have a color feeling.
Whitepoint white point: A reference point for color balance measurement purposes in color separation, photography, or photography.
Xenon-arclamps xenon lamp: A commonly used light source for color meters and spectrometers, which is used to simulate sunlight because it has an almost continuous emission spectrum in the ultraviolet and visible range.
Yuv: A uniform color system that is commonly used in the color display industry.
Zonetheory zone theory: A process of color vision transfer processing that links the three-color doctrine of the human eye with the doctrine of opposite colors. Judd first proposed it in 1949.
