Increasing the Sharpness can increase bandwidth usage. A sharper image might increase image noise especially in low dynamic
conditions. A lower setting reduces image noise, but the whole image will appear less sharp.
Exposure Settings
Congure the exposure settings to suit the image quality requirements in relation to temperature variations in the scene.
Automatic gain control - This setting is used to automatically adjust the gain to an appropriate range, the weaker the image signal,
the stronger the gain. Select the Linear or Equalization automatic gain control method. The latter uses a histogram equalization
method, which adjusts the gain dynamically by distributing the most frequent intensity values.
Exposure zones - This settings determines which part of the image is used to calculate the exposure. For most situations, the Auto
setting can be used. For particular requirement, select Dened and then click Edit and select one of the predened areas.
Gain - This setting controls the maximum gain. Lowering the gain reduces the contrast in the thermal image.
