Peak Detector
The "Peak Detector" is a fast method for defining individual input levels, and can
improve the accuracy of input levels set by the Auto Input Level function. Enabling
the "Peak Detector" activates a special operating mode for detecting only pixels that
are considered black or white—all other levels are displayed as a mid-level gray.
When used with a 16-step grayscale pattern in which the two black and white bands
are known to be at opposite edges of the image, you can watch these isolated areas
while adjusting individual blacklevels and input drives until both bands are just
visible. Images from this source will then display correct blacks and whites without
crushing or washing out.
NOTE: If using Peak Detector with PIP, both images must have the same color
space.
Level Detector
The "Level Detector" checkbox enables specific thresholds for blacks and whites—
input levels that fall below a specified Level Value (see below) are displayed as
black, and all others are displayed as white. It aids in Odd Pixel Adjustment. To use:
1. Enable "Level Detector" and display a continuous grayscale.
2. Set "Level Value" to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set "Level Value" to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
Level Value
Level Value defines the value to be used by the Level Detector in recognizing blacks
and whites. See Level Detector, above.
LiteLOC™ Calibration
NOTES: 1) LiteLOC™ Calibration takes up to two minutes. 2) For best results, allow
the projector to warm up for 15 minutes prior to calibration.
LiteLOC™ Calibration defines the range of power needed to maintain lamp
brightness. Select Calibrate LiteLOC for calibration using your projector's unique
specifications (recommended) rather than standard specifications. The projector will
revert to the default back-up in the event of a power failure.
'
The two "Option
Card" entries In the
Configuration
menu identify
which optional
input modules
(a.k.a. cards) are
present at
INPUT 5
(Option 1) and
(Option 2).
INPUT 6
If either of these option slots are empty, the corresponding read-only menu entry does
nothing. If there is a module installed, the corresponding menu entry may activate a
submenu of further options pertaining to that module.
