3D LUT (3 dimensional look up table) A mathematical description of colors
with red, green, and blue on the x, y, and z axis, respectively,
forming a cube. The Display Manager System creates 3D LUTS
based on the characterization of your display. You can export 3D
LUTs for use by supported imaging products.
bias A monitor setting that determines the electrical current to the
monitor.
black point The darkest color that a display device can display. Not necessarily
true black.
brightness The measurement of both the saturation and luminance of a color.
calibration The process of adjusting the monitor’s white and black points as
close as possible to aim points. During automatic calibration in the
Display Manager System, these adjustments are done via the
enable cable. During manual calibration, the user makes the
adjustments from the monitor controls. Calibration is a foundation
for creating a profile of the display.
characterization The measurement of the color characteristics of a display. This
results in the creation of a .chr file that describes how the device
displays colors. The Display Manager System Viewer uses this file
to create a 3D LUT. Also referred to as profiling.
chromaticity
coordinates
Coordinates that specify position in a chromaticity diagram. The
chromaticity coordinates of a stimulus are derived from its
tristimulus values by taking the ratio of each of the tristimulus
values to their sum; i.e. x=X/X+Y+Z, y=Y/X+Y+Z, where x and y
are the chromaticity coordinates and X,Y, and Z the tristimulus
values.
chromaticity
diagram
A two dimensional plot of (three dimensional) color space depicting
the (three dimensional) relationship among colors perceived by the
normal human visual system. This plot most commonly includes a
"horseshoe" which defines the spectral locus (the range of colors
visible to the human observer). Colors are indicated on the plot by
x, y chromaticity coordinates which correlate to color attributes.
CIELab A device independent color space that defines colors according to
lightness (L), redness/greenness (a), and yellowness/blueness (b).
color gamut See gamut.
