GLOSSARY

Keystone ➤		A distortion of the image which occurs when the top and bottom borders of
		the image are not equal in length. Side borders slant in or out, producing a
		keystone shaped image.
Learn Screen ➤		An ACON function which stores screen position data in memory for future
		reference. Learn Screen is usually performed only once per projector installa-
		tion. If the ACON Locator Assembly or screen is moved (i.e., the projector
		installation changes to ceiling mount), the Learn Screen function must be
		repeated.
Linearity	➤	The reproduction of the horizontal and vertical size of characters and/or
		shapes over the entire screen.
Line of Best	➤	When light from a projector is incident on a screen, the light reflects from
Viewing		the screen such that the angle of reflection equals the angle of incidence.
		The Line of Best Viewing is along the line of reflection.
Locator Assembly ➤		The Locator Assembly, situated on the front of the projector, is the "eye"
		of the ACON system. It includes a photosensor/lens component which
		mechanically scans the projected display at each convergence point while
		sensing relative positions of each projected color.
Loopthrough ➤		The method of feeding a series of high impedance inputs from a single
(Loopthru)		video source with a coaxial transmission line in such a manner that the line
		is terminated with its characteristic impedance at the last input on the line.
Lumen ➤		The amount of visible light emitted by a light source is measured in lumens.
Lux ➤		The amount of visible light per square meter incident on a surface.
		1 lux = 1 lumen/square meter = 0.093 foot-candles
Menu ➤		A list of options which are displayed on the screen for selection by the user.

NTSC Video ➤ A video output format of some video tape and disk players. There are two types of NTSC (National Television Standards Committee) video: NTSC

3.58and NTSC 4.43. NTSC 3.58 is used primarily in North America and Japan. NTSC 4.43 is less commonly used.
