GLOSSARY

 

 

 

 

 

 

 

 

 

Autolock

The ability of the projector to automatically synchronize to the horizontal

 

 

 

and vertical scan frequencies of an input signal.

Bandwidth

The frequency range of the projector's video amplifier.

Blanking Time

The time inside one scan line during which video is not generated. The

 

 

 

blanking time of the input signal must be equal to or greater than the

 

 

 

retrace time of the projector.

 

Bow

A horizontal curve in the center of the image, and/or a vertical curve across

 

 

 

an image.

Brightness

Brightness in projection usually describes the amount of light emitted from

 

 

 

a surface such as a screen. Brightness is measured in lumens, foot-lamberts,

 

 

 

foot-candles, or lux.

Candela or Candle

The intensity of light is measured in candelas.

Channel

A 2-digit number with user-assigned source input information. This infor-

 

 

 

mation includes a physical input (switcher, slot), a setup memory (input

 

 

 

or recall), and a name or description. Assignments are made through the

 

 

 

Channel List.

Channel List

A list of up to 99 channels (explained above) which may be created, edited,

 

 

 

or deleted by the user. The Channel List feature provides an alternative, and

 

 

 

sometimes easier, way to select sources and their setups.

Color Shift

The change in the tint of a white field across an image.

Color Temperature

This term refers to the coloration (reddish, white, bluish, etc.) of a white

 

 

 

image. (It does not refer to the brightness of a white image.) The Kelvin (K)

 

 

 

temperature scale is used to measure color temperature.

Color Temperature

The accuracy of color temperature at any location.

Uniformity

 

 

Composite Video

This term refers to the output of video tape players and some computers.

 

 

 

Synchronization, luminance, and color signals are combined on one

 

 

 

output cable.
