SPECTRAVIEW II - USER’S GUIDE
Gamma
– The relationship between the input video signal to a display monitor and the screen
output luminance. Typically the screen luminance follows a mathematical power function of the
input video signal, the exponent of which is called the gamma.
Gamut
– The range of colors that can be reproduced on a particular device such as a monitor
or printer, or that can be distinguished by a sensing device such as a scanner or the human
eye.
Hue
– The basic attribute of color such as red, green, yellow, blue or purple.
ICC
– International Color Consortium, a color industry group working on standards for color
management technology.
ICC Profile
– A file conforming to the standards set by the ICC that contains a description of
the color characteristics of a device such as a monitor, printer, or scanner. In Windows ICC
profiles have the file extension “.icm”.
Image Color Management (ICM)
– The Color Management System built into the Microsoft
Windows operating systems.
Intensity
– Intensity specifies the luminance or brightness of white when displayed on the
screen.
Kelvin
– An absolute temperature scale denoted by K. Zero Kelvin (0K) is equivalent to –273°
Celsius.
Lab
– (See CIE Lab)
LED
– Light Emitting Diode.
LCD
– Liquid Crystal Display.
Lightbox
– An enclosure with controlled lighting conditions used to evaluate proofs, transpar-
encies and other printed materials. Typically a lightbox is illuminated to approximate a standard
illuminant such as D50 or D65.
Luminance
– A measure of the brightness or intensity of light, usually expressed in units of
Candelas per meter squared (cd/m
²
) or foot Lamberts.
Look Up Table (LUT)
–
A table used to translate input values to output values.
SpectraView
displays use 10 or 12 bit internal LUTs to apply Gamma corrections and Tone Response
Curves.
MCS (Monitor Calibration Settings) file
– A file used by SpectraView II to store the results of
the calibration, including the monitor settings and measurements.
Metamerism
– A phenomenon in which two color samples appear to match in color under cer-
tain lighting conditions but not in others.
MPCD (Minimum Perceptible Color Difference)
–
A unit of measure, developed by the CIE,
to define the change in light and color required to be just noticeable to the human eye.
Nit
– A unit of luminance equal to Candelas per meter squared (cd/m
²
).
NTSC
– National Television Standards Committee. A standard for encoding video signals used
widely in North America and Japan.
