Glossary
This appendix defines many of the terms used in this manual as they apply to the
A
ccurate projection system.
ACON (Automatic Convergence)>
ACON is an optional automatic convergence feature available for Accurate series
projectors. With ACON installed, convergence of the red, green and blue images are
performed accurately and automatically with minimal user intervention.
ASI (Automatic Source Interpolation)>
A process whereby a display setup for a given source is approximated from other setups
already in memory. For more information about ASI, refer to the ASR entry in section
3.7,
Utility Features.
ASR (Automatic Source Recall) >
A process whereby a display setup for a given source is chosen from memory according
to its signal parameters (horizontal and vertical frequencies). For more information about
ASR, refer to the ASR entry in section 3.7,
Utility Features.
Active Line Time >
The time, inside one horizontal scan line, during which video is generated.
Ambient Light >
The ability of a screen to reject ambient light in a direction away from the Rejection ''line
of best viewing''. Curved screens usually have good ambient light rejection. Flat screens
usually have less ambient light rejection.
Analog Video >
The video output of most computers and video tape machines. Analog video can generate
a large number of colors.
Aspect Ratio >
The ratio of the width of an image to its height.
Automatic Convergence >
The automatic alignment of the projected red, green and blue images on the projection
screen.
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.
