Using Image Alignment
Image alignment is an automatic adjustment that occurs as you focus the
infrared camera lens. The visible light image and the infrared image are lined
up based on the focusing distance of the infrared lens so that they may be
combined for viewing and analysis. The visible light image and the infrared
image are lined up for distances greater than 50 cm (approximately 2 ft).
Focusing
Prior to capturing images using the visible light module and IR Fusion, it is
important to make sure the target object is in focus. As you rotate the infrared
(IR) lens to focus the camera, if the IR blend is less than 50%, the IR Fusion
blend level changes to 50% infrared and 50% visible light (VL). Once you
have the target object in focus and stop rotating the IR lens, the IR Fusion level
returns to your setting. You can focus the infrared portion of the image only;
the focus of the VL portion is set at the factory.
To focus the camera, remove the IR lens cap, point the lens at the target, and
manually rotate the infrared lens with your finger. Focus by aligning the edges
of the IR and VL images.
Adjusting IR-VL Fusion Blend Level
Note
This feature is not available on the Ti40.
You can change the IR Fusion blend level from full infrared (IR) to full visible
light (VL) or some combination in between. When the IR Fusion blend level is
set to full IR, 100% of the image is IR. When the IR Fusion blend level is set
to full VL, 100% of the image is VL. When the IR Fusion blend level is set
somewhere in the middle of full IR and full VL, an appropriate amount of the
image is IR and an appropriate amount is VL, thus displaying a fused—or
blended—image.
To adjust the IR-VL Fusion blend level using the level & span button and
mouse controller:
1. Press and hold G until the IR Fusion level dialog box appears near the
bottom of the screen.
