Use the Advanced Image Settings
submenu to make the adjustments
necessary for lesser-used but more
specialized applications on your
projector.
NOTE: 3D Source option is only
available for Mirage HD.
This control applies
GAMMA TABLE:
a default video, graphics or simple gamma table or "curve" to your images,
controlling the intensity of mid-level colors and producing maximum contrast,
brightness and color performance. As shown at right, the graphics curve is a modified
power curve that will show more detail in darker areas of the projected content 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 true power curve that does
not alter the contrast or the intensity of mid-level colors. 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.
Different values (1-3) here indicate that the original gamma table has been adjusted
with either the Gamma slide bar or direct key.
NOTES: 1) If no user curves have been defined and downloaded to projector memory,
only the 2.2 default gamma curve is available here – adjust as desired using gamma
in the main Image Settings menu. 2) Some graphic material will look best with the
video setting while some video material is best with the graphic setting.
SELECT COLOR ADJUSTMENT:
choose an overall color palette for all images. The "Max
Drives" factory default simply drives all three colors at their
maximum level so that they are fully on and cannot be
changed. The two other pre-defined color adjustment
choices—SD Video and HD Video—apply a color gamut
optimized for video sources (standard or high-definition).
Alternatively, you can specify a color temperature. This
enables the adjacent Color Temperature slide bar and applies
.
