Section 1: Introduction
CANDELA OR CANDLE
Unit of measure for measuring intensity of light in certain types of projectors.
CHANNEL
A collection of measurements stored by the projector for a given input source, including frequencies, pulse width,
polarity, syncs, channel number and location, user-adjustable display settings, etc. Use channels to switch between a
variety of setups quickly, automatically recalling previously defined display parameters.
CHANNEL LIST
A list/menu of previously defined channels available in projector memory.
CHANNEL NUMBER
A number that uniquely identifies a specific channel retained in projector memory. The projector (via its TPC) offers up
to 8 channel choices at once.
CHECKBOX
A menu item that indicates whether an option is currently in effect (checked) or not (unchecked).
CHROMINANCE
The signal representing the color information (hue and saturation) when the image is represented as separate
chrominance and luminance. Same as "chroma".
CLEAN APERTURE
The fraction of a motion picture frame image that is intended to be viewed by the audience. The clean aperture is
subjectively free of edge artifacts and lies within the screen area framed by curtains in a cinema. Aspect ratio is often
referenced to the clean aperture.
COLOR GAMUT
The range of colors allowed in a specific system, as defined within a triangular area located on the CIE color locus
diagram whose corners are the three primaries defined in the system. Also known as color space.
COLOR SHIFT
A change in the tint of a white field across an image.
COLOR TEMPERATURE
The coloration (reddish, white, bluish, greenish, etc.) of white in an image, measured using the Kelvin (degrees K)
temperature scale. Higher temperatures output more light.
COMPONENT VIDEO
Refer to YcbCr or YPbPr.
