time).
The IR camera adjustments to the region of interest (ROI) determine what portion of the image is
used by the Automatic Gain Control (AGC) algorithm. By default all of the pixels in the image are
considered; in some cases it may provide an improved image if a portion of the image is excluded.
For example, the sky is generally very cold, so if the ROI excludes the sky it may add more contrast
to the rest of the image. A pull-down list offers some convenient options.
When Custom is selected, a handle is
shown in the center of the screen.
Drag the handle to set
the size of the ROI box.
Drag the ROI box over
the portion of the scene
that will control the AGC.
AGC
The AGC parameters affect how the overall IR video image appears. A combination of manual
adjustments may provide a more appealing image, depending on personal preferences. Be aware
that the settings that are optimal at one time may be less optimal a short time later, since conditions
such as weather and time of day affect the image and are constantly changing.
Note
The Video Analytics default AGC Mode parameters are invoked when analytics is enabled. If
parameters have been changed while analytics is disabled, they will be changed to the VA defaults
when analytics is enabled again, but will be saved and invoked when analytics is disabled.
