Section 3: Operation
Level Detector
The Level Detector check box enables a 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
The Level Value defines the value to be used by the Level Detector in recognizing blacks and whites. See
Detector, above.
Aspect Ratio Overlay
Selecting this option with a check mark will overlay a number of common aspect ratio boxes on top of the
source image. This is very helpful during the setup of the projector and can be turned OFF after desired
specifications have been achieved.
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. Refer to the
Lamp menu for more details.
Intelligent Lens System (ILS
This option allows you to choose between 3 types of lens calibrations. Reference calibration determines a
reference point that is used as a defined starting position for relative motion of the lens. All positioning is
measured from this reference point. A reference calibration is lost when power is removed from the projector
and will occur on every power up as long as ILS
tics of each motor and values are saved in the projector's memory. If ILS
has previously been done, the projector will automatically recall these settings from memory when it's being
powered up and a motion calibration will not take place. A full calibration performs both a reference and
motion calibration.
Automatic ILS
TM
When this option is selected (default) and the projector is in ILS mode, the projector will perform a lens
calibration on each power-up. During calibration, the shutter will be closed and the status LED will display
'LC'. If ILS is not selected, the ALC setting will be ignored. If, during power-up, ALC is not selected and
TM
ILS is, the last stored location from the previous ILS
TM
will moved to that position upon power-up if necessary.
