GAMMA TABLE:
This control applies a default
video
,
graphics
or
simple
gamma table
or “curve” to your images, controlling the intensity of midlevel colors and producing
maximum contrast, brightness and color
performance. As shown at right, the
graphics curve is a simple power curve
while the video curve has a linear segment
near black to compensate for increased
black levels typical of video signals. A
simple gamma curve is a value of 2.2 and is
correct for most signal conditions. Although
the projector automatically applies either the graphics or video curve according to
what type of incoming signal is detected, in some cases you may wish to override this
default and use
graphics
gamma for a video source or
video
gamma for a graphics
source. Alternatively, if neither default is ideal, you may prefer to apply the simple
(non-optimized) gamma curve or a user-defined custom gamma curve that has been
created externally, named, and downloaded to the projector (requires separate PC-
based
Arbitrary Gamma
and
KoRE Librarian
software applications). If any of these
special user curves have been installed, their names will appear in the Gamma Table
pull-down list.
Keep in mind that any
Gamma Table
choice sets the related
Gamma
value (shown in
the
Image Settings
menu) to a 2.2 default, where it can be fine-tuned as desired.
