Setup->IR->ROI (region of interest)
The camera adjustments under the ROI
heading allow the user to make changes to
the Region Of Interest. The ROI determines
what portion of the image is considered 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. A pull-down list offers some
convenient options.
Setup->IR->AGC
The AGC parameters affect how the overall IR video image appears. Using the AGC button on the
Live Video page (refer to “Toggle Automatic Gain Control (AGC)” on page 26), toggle through AGC
Scene Presets. The default presets are suitable for most installations, but in some cases other
selections may provide a more appealing image, depending on personal preferences. Be aware
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.
• Brightness (ITT Mean) setting determines the temperature that is at the middle of the 256
“shades of gray” produced by the AGC. Positive values allow more detail in hotter scen
es,
while negative values allow more detail in lower temperature scenes. Range is -4 to 4.
• Contrast (Max Gain) can be used to increase contrast, especially for scenes with little
temperature variation (it may also increase noise due to increased gain). Range is 12 to 24.
• Sharpness (DDE Gain) is used to enhance image details and/or suppress fixed pattern noise.
Positive values increase Sharpness, while negative values soften the image and filter fixed
p
attern noise. A setting of 0 is neutral and will not have any effect. Range is -10 to 40.
• AGC Filter determines how quickly a scene adjusts when a hot object appears (or disappear
s)
within the AGC ROI. If set to a low value, the A
GC will adjust more slowly to a hot object
entering the scene, resulting in a more gradual transition. Range is 1 to 32.
