'
A number that uniquely identifies a specific channel retained in projector memory.
The projector can retain up to 99 channels.
'
A menu item that indicates whether an option is currently in effect (checked) or not
(unchecked).
'
The signal representing the color information (hue and saturation) when the image is
represented as separate chrominance and luminance. Same as "chroma".
'
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.
'
An optical component, the color wheel is made up of red, green and blue and
sometimes white segments. The light generated by the lamp is sequentially filtered by
the color wheel (as it's spinning) into R, G, B color primaries and passed to the DMD
which then creates an image for each color.
'
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 elements of a projected image so that they
appear as a single element.
'
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.
'
The Display Data Channel VESA standard enables communication between PCs and
monitors, and is based on E-EDID protocol.
'
A "direct digital interface" signal can be supplied to the projector via an optional
digital input module installed in
259M signal using a Serial Digital Input Module or input an SMPTE-272M signal
from a Digital HDTV Serial Input Module.
