VistaGRAPHX 2500 User's Manual

A menu item that indicates whether an option is currently in effect (checked) or
not (unchecked).

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 (K) temperature scale. Higher temperatures output
more light.

See YUV Video.

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.

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

°

Digital Micromirror Devices



used in the VistaGRAPHX 2500 for processing

red, green, and blue color data.

An optional device in the VistaGRAPHX 2500 that converts NTSC 3.58, NTSC
4.4, PAL, PAL-N, PAL-M, or SECAM to RGB video.

The sharpness of a display from a video source.

A type of rear-projection screen which spreads the light striking it. Screen gain is
less than 1 but audience viewing angles are increased.

An adjustment that affects the display of an image. Such display settings include
contrast, brightness, tint, blanking, focus, etc.

A very rapid variation in image brightness caused by a frame rate that is too
slow. (See Interlace.)

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.

The intensity of visible light per square foot.

The luminance (brightness) which results from one foot-candle of illumination
falling on a perfectly diffuse surface.

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.
