GLOSSARY
Display Setting
>
The level of a display adjustment. Some display adjustments are: Contrast, Brightness,
Blanking, Bow, Size. Keystone, Pincushion, Focus and Convergence.
Flicker
>
A rapid variation in brightness created when the frame rate is too slow. (See also
Interlace.)
Frame
Rate
>
The frequency at which complete images are generated. For non-interlaced
signals, the frame rate is identical to the vertical frequency. For interlaced
signals, the frame rate is one half of vertical frequency.
Foot-candle
>
The intensity of visible light per square foot.
1 foot-candle
=
1 lumen/square foot
=
10.76
lux
Foot-lambert
>
The luminance (brightness) which results from one foot-candle of illumination falling on
a perfectly diffuse surface.
Gain or Screen
Gain
>
The ability of a screen to direct incident light to an audience. A flat matte white wall has
a gain of approximately 1. Screens with gain less than 1 attenuate incident light; screens
with gain more than 1 direct more incident light to the audience but have a narrow
viewing angle. For example: An image reflecting off a 10 gain screen appears 10 times
brighter than it would if reflected off a matte white wall. Curved screens usually have
larger gain than flat screens.
Gamma Correction
>
A feature provided on
Accurate Series,
9 and 8 models which boosts the blue color output
when required to provide improved picture intensity and color uniformity.
Geometry
>
The reproduction of a straight and rectangular image.
Help Page
>
A display of help information on the projection screen.
Horizontal
Frequency
>
Also called horizontal scan rate or line rate, this is the frequency at which scan lines are
generated. Horizontal frequencies vary amongst sources.
Hot Spot
>
A circular area of a screen where the image appears brighter than elsewhere on the
screen. The hot spot always appears located along the line of sight and ''moves'' with the
line of sight. High gain screens and rear screens designed for slide or movie projection
usually have a hot spot.
Input
>
A physical connection route for a source signal defined by two numbers', a
switcher
number
and a
slot number.
If the switcher number is 0, the input is a rejector input.
Image
Shifter Module
>
An optional interface module which can lengthen CRT life while maintaining a bright
picture by slowly shifting the image about the CRT faceplate. Image shifting occurs both
horizontally and vertically. Shift range is totally controllable by the user. NOTE:
Standard on the Model 9.
