|
Color Management |
The use of software, hardware and procedures to measure and control color in an imaging system, including capture and display devices. |
|
|
Digital Color |
Color that has been translated into a set of numbers for software tointerpret and compare |
|
|
Color Specifier |
The original source of the color targetto be reproduced in manufacturing. |
|
|
Color Formulation Software |
This is software that is designed to assist in mixing spot colors forprinting and with paints. |
|
|
Color Profiling Software |
This is software designed to define theCMYK color output capability of a CMYK printing device |
|
|
Iris |
The colored part of the eye |
|
|
Pupil |
The part of the eye that allows light to be let in. Varies in size depending on the level of light. |
|
|
Cornea |
Transparent cover over the lens of the eye. Cornea and lens work together to focus an image |
|
|
Sclera |
white fibrous outer wall layer of the eye |
|
|
Lens |
The flexible transparent body over the eye |
|
|
Macula |
An oval-shaped pigmented area near the center of the retina |
|
|
Vitreous Humor |
Jellylike fluid fills interior of eye |
|
|
Fovea |
Visual center of the eye where resolution is most powerful |
|
|
Choroid |
Inner lining of eye which is coated with a black pigment |
|
|
Retina |
Contains the light-sensitive cells of the eye. Provides the smooth surface upon which the image can be focused |
|
|
Ciliary Muscles |
changes shape of the cornea and changes position of the lens to focus light for near and far vision |
|
|
photoreceptors |
Between the choroid and the nerve network of the retina. Contain rods and cones |
|
|
Rods |
effects the blue tones. |
|
|
Cones |
provide better rendition of definition |
|
|
Trichromatic Perception |
Humans see RGB |
|
|
Far Sighted |
farsighted people see distant objects clearly |
|
|
Near Sighted |
Focus on near objects
|
|
|
Astigmatism |
the cornea or lens is irregularly shaped |
|
|
Photon |
a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass |
|
|
wavelength |
the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave |
|
|
frequency |
the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second |
|
|
Amplitude |
the maximum difference of an alternating electrical current |
|
|
Electromagnetic radiation spectrum |
the complete range of the wavelengths of electromagnetic radiation, beginning with the longest radio waves (including those in the audio range) and extending through visible light (a very small part of the spectrum) all the way to the extremely short gamma rays |
|
|
opacity |
how much light is blocked or absorbed by material |
|
|
Nanometer |
the unit of which light wavelengths are measured |
|
|
Visible Spectrum Wavelengths |
380-780 nm |
|
|
UV |
Ultraviolet light with wavelengths between the optical and X-Rays |
|
|
IR |
Infra-Red wavelengths longer than red light. Infrared radiation is electromagnetic energy that is absorbed by the object |
|
|
Logarithmic Scale |
used to condense a very large range of quantities into a more manageable size |
|
|
Refraction |
A breakdown of the different wavelengths is only visible under certain circumstances |
|
|
Color Temperature |
a way to express the purity of white light, or the color cast of white light |
|
|
Illuminant |
tables of spectral energy distributions intend to represent real light sources |
|
|
Black body |
A theoretical object that absorbs all of the light radiation that falls on it |
|
|
Degree Kelvin |
color temperature is measured |
|
|
ISO 3664:2009 |
specifiesviewing conditions for images on both reflective and transmissive media, such as prints (bothphotographic and photomechanical) and transparencies, as well as imagesdisplayed in isolation on colour monitors |
|
|
White Point |
Color temperature |
|
|
Spectral Power Distribution |
SPD- a data profile of the color of a light source or measured color sample |
|
|
Spectral Response Curve |
Shows the energy emitted by a light source at each wavelength or band of wavelengths over the visible spectrum |
|
|
Metamerism |
how the same color will appear different under two different light sources, or when surrounded by different colors. |
|
|
Spectrophotometer |
Measures the spectral responsive curve of a color sample which has been illuminated by a known standard light source |
|
|
CIE |
international commission on illumination established a standard way of quantifying color |
|
|
L*a*b* |
A more uniform version of CIE was defined in 1976, officially known as CIE L*a*b*. L* stands for luminance, a* is the red-green axis, and b* is the blue-yellow axis. |
