Focus Area options
Focus Area is related to Auto Focus. By default, MUVIS attempts to focus on the center of your image. You can change the default focus area by right-clicking on either a visible or UV image and dragging the cross-hair to the desired location. Click View to see the current Auto Focus area. Click Reset to undo any changes you have made.
Leveling area options
The Leveling section is where you set the default low and high thresholds for both visible and UV imaging. For more information, see Using the Leveling Histogram.
