Use the Advanced Image Settings
submenu to adjust lesser-used options
required only for more specialized
applications.
GAMMA TABLE:
This control applies
a default video or graphics gamma table or “curve” to your images, controlling the
intensity of midlevel colors while
maintaining 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
blacklevels typical of video signals.
Although the
Cine-IPM 2K automatically
applies either the graphic 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 a
user-defined custom gamma curve that has been created externally, named, and
downloaded to the
Cine-IPM 2K (requires separate PC-based Arbitrary Gamma and
KoRE Librarian software applications). If any 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 2.22 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 slidebar or direct key.
SELECT COLOR ADJUSTMENT:
In “Select Color
Adjustment”, choose an overall color performance for all
non-cinema images. The “Max Drives” factory default
simply drives all 3 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 non-cinema video
sources (standard or high-definition). Alternatively, you can
specify a color temperature, which enables the nearby Color
Temperature slidebar and applies its current setting (default = 6500K).
