Glossary
Following is an explanation of some of the terms used in this guide which may be unfamiliar or which were 
not explained in the manual itself. Further information can be obtained by referring to other commercially-
available publications.
3-2 pull-down 
functionThis function directly converts image sources that have been recorded in the same 24-frame 
format used for movies into 60-frame progressive signals. This allows data such as DVD 
software that has been recorded in 24-frame format to be played back on large screens with 
more natural and accurate reproduction, without any loss of image quality from the original 
movie.
Aspect ratioThe ratio between an images length and its height. HDTV images have an aspect ratio of 16:9 
and appear elongated. The aspect ratio for standard images is 4:3.
Black & white 
extension functionA function that accentuates differences in color gradations (darkness an lightness of colors) 
even for images that are very dark or very bright, to make them easier to view.
Color 
difference 
signal 
(component)A type of video signal output by video equipment which actually consists of three separate 
signals: a red + luminance signal (R-Y), a luminance signal (Y) and a blue + luminance signal 
(B-Y). Each signal is transmitted along a separate cable. Color difference signals generally 
result in a better image than composite signals (in which the red, green and blue signals and 
the luminance signal are all transmitted along a single cable).
Color 
temperatureThe temperature of an object which is emitting light. If the color temperature is high, the 
colors tend to take on a bluish tinge. If the color temperature is lower, the colors tend to take 
on a reddish tinge.
Component videoVideo signals which have the video brightness signals and color signals separated, in order to 
provide better image quality.
In high-definition TV (HDTV), it refers to images which consist of three independent signals: 
Y (luminance signal), and Pb and Pr (color difference signals).
Composite videoVideo signals which have the video brightness signals and color signals mixed together. The 
type of signals commonly used by household video equipment (NTSC format).
The signals consist of the carrier signal Y (luminance signal) and the chroma (color) signal 
which are contained in the color bar signal.
ContrastThe relative brightness of the light and dark areas of an image can be increased or decreased 
in order to make text and graphics stand out more clearly, or to make them appear softer.
Cool-downThe cooling process for the projector lamp continues even after the [Power] button on either 
the remote control or the projectors control panel has been pressed to turn off the projector. 
All button operations for the emote control and the projectors control panel are disabled 
while the cooling fan is operating at this time. The length of time that this is happening is 
called the cool-down period. The cool-down period lasts for about 2 minutes. The actual 
time will vary depending on the external air temperature.
DCDi functionAn abbreviation for Directional Correlational Deinterlacing. Refers to a high-resolution 
image circuit function developed by Faroudja. It incorporates the latest in edge cutting 
technology to smooth the jaggedness from the edges of images that have been converted from 
interlaced to progressive video, in order to provide more natural images.
DFPAbbreviation for Digital Flat Panel. Refers to a standard method for digital transmission of 
video signals.
Dolby DigitalA proprietary sound format developed by Dolby Laboratories. Normal stereo is a 2-channel 
format that uses two speakers. Dolby Digital is a 6-channel (5.1 channel) format that adds to 
this a center speaker, two rear speakers and a sub-woofer.
DV IAbbreviation for Digital Visual Interface. Refers to a standard method for digital transmission 
of video signals.
DVI is a standard which has also been applied to digital household electronic equipment other 
than computers. It allows images to be transmitted at higher resolutions than for DFP.
Film judgment 
functionThis function determines whether or not the video source is a 24 Hz progressive film source.
GainThe adjustment of minute changes in color that occur as result of factors such as differences 
in the equipment used to display images. It adjusts the coloration in brighter ranges separately 
for R, G and B components.
GammaThe adjustment of minute changes in color that occur as result of factors such as differences 
in the equipment used to display images. It adjusts the coloration in intermediate ranges 
separately for R, G and B components. 
						

							Glossary

HDTVAn abbreviation for High-Definition Television. It refers to high-definition systems which 
satisfy the following conditions.
•
•• •Vertical resolution of 750p or 1125i or greater 
(p = progressive scanning, i = interlaced scanning)
•
•• •Screen aspect ratio of 16:9
•
•• •Dolby Digital audio reception and playback (or output)
InterlacedA method of image scanning whereby the signal bandwidth used is approximately half that 
required for sequential scanning when images with the same still picture resolution are 
broadcast.
OffsetThe adjustment of minute changes in color that occur as result of factors such as differences 
in the equipment used to display images. It adjusts the coloration in darker ranges separately 
for R, G and B components.
Refresh RateThe light-emitting element of a display maintains the same luminosity and color for an 
extremely short time. Because of this, the image must be scanned many times per second in 
order to refresh the light emitting element. The number of refresh operations per second is 
called the refresh rate, and is expressed in hertz (Hz).
S-Video imagesA video signal which has the luminance component and color component separated in order 
to provide better image quality.
It refers to images which consist of two independent signals: Y (luminance signal), and C 
(color signal).
SDTVAn abbreviation for Standard Definition Television. It refers to standard television systems 
which do not satisfy the conditions for High-Definition Television.
Security lockA device consisting of a protector case with a hole in it that a commercially-available theft-
prevention cable can be passed through in order to secure the device to a table or pillar. This 
projector is compatible with the Microsaver Security System manufactured by Kensington.
sRGBAn international standard for color intervals that was formulated so that colors which are 
reproduced by video equipment can be handled easily by computer operating systems (OS) 
and the Internet.
SVGAA type of image signal with a resolution of 800 (horizontal) x 600 (vertical) dots which is 
used by IBM PC/AT-compatible computers (DOS/V computers).
SXGAA type of image signal with a resolution of 1280 (horizontal) x 1024 (vertical) dots which is 
used by IBM PC/AT-compatible computers (DOS/V computers).
Synchronization 
(Sync.)The signals output from computers have a specific frequency. If the projector frequency does 
not match this frequency, the resulting images will not be of a good quality. The process of 
matching the phases of these signals (the relative position of the crests and troughs in the 
signal) is called synchronization. If the signals are not synchronized, problems such as 
flickering, blurriness and horizontal interference can occur.
TrackingThe signals output from computers have a specific frequency. If the projector frequency does 
not match this frequency, the resulting images will not be of a good quality. The process of 
matching the frequency of these signals (the number of crests in the signal) is called 
“tracking”. If tracking is not carried out correctly, wide vertical stripes will appear in the 
projected images.
Three-dimensional 
Y/C separationA term given to the reduction in fine image distortion such as stripiness and jaggedness of 
image contours  that can occur as a result of separate digital processing of Y (luminance) and 
C (chroma) components of image signals.
UXGAA type of image signal with a resolution of 1600 (horizontal) x 1200 (vertical) dots which is 
used by IBM PC/AT-compatible computers (DOS/V computers).
VGAA type of image signal with a resolution of 640 (horizontal) x 480 (vertical) dots which is 
used by IBM PC/AT-compatible computers (DOS/V computers).
XGAA type of image signal with a resolution of 1,024 (horizontal) x 768 (vertical) dots which is 
used by IBM PC/AT-compatible computers (DOS/V computers).
YCbCrThe carrier signal which is contained in the color bar signal used in modern TV transmissions 
(NTSC format). The name comes from the Y (luminance) signal and the CbCr (chroma 
[color]) signals.
YPbPrThe carrier signal which is contained in the color bar signal used in high-definition TV 
(HDTV) transmissions. The name comes from the Y (luminance) signal and the PbPr (color 
difference) signals.
