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.
A change in the tint of a white field across an image.
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.
See YCbCr or YPbPr .
The output of video tape players and some computers, characterized by
synchronization, luminance and color signals combined on one output cable.
The degree of difference between the lightest and darkest areas of the image.
The alignment of the red, green, and blue light elements of a projected image so that
they appear as a single element. In this projector, convergence can be adjusted by
Christie service personnel only.
A projection screen which is slightly concave for improved screen gain. Curved
screens usually have screen gains which are greater than 1 but viewing angles much
less than 180
°
. Curved screens are not recommended for use with this projector.
Digital Cinema Distribution Master. A file or collection of files formatted for
exhibition and comprised of all the components of the
title . A reference size of about
200 GB per title is likely.
The Display Data Channel VESA standard enables communication between PCs and
monitors, and is based on E-EDID protocol.
Digital Micromirror Devices
™
used in this projector for processed red, green, and
blue color data.
Digital Source Master. A title’s native source files in acquisition format, edited to
create the distribution master and for reformatting for NTSC, HDTV, DVD, etc., and
potentially archived.
The Digital Visual Interface standard signal supplies analog or digital RGB, sync,
I
2
C, and clock information to the processing electronics in the projection head.
The sharpness of a display from a video source.
A type of rear-projection screen which spreads the light striking it. Screen gain is
typically less than 1 but audience viewing angles are increased. Rarely used in
cinema.
Professional public presentation of theatrical content by electronic means,
particularly emphasizing projectors whose image source is digital data. Also known
as d-cinema and (rarely) e-cinema.
Also known as digital scaling. The process of averaging pixel information when
scaling (resizing) an image up or down. When reducing the size of an image, adjacent
pixels are averaged to create fewer pixels. When increasing the size of an image,
