14.3.4 Calibrating the camera

14.3.4.1 General
The calibration of the camera is performed as a non-uniformity correction (NUC). An
NUC is an image correction carried out by the camera software to compensate for differ-
ent sensitivities of detector elements and other optical and geometrical disturbances
Calibration is needed whenever the output image becomes spatially noisy. This may, for
example, happen when the ambient temperature changes.
The calibration can be carried out automatically, with different selectable intervals. It is al-
so possible to perform a calibration manually.

14.3.4.2 Automatic calibration

To set the automatic calibration, follow this procedure:
1. On the upper toolbar, click the Periodic calibration icon
box with radio buttons.
2. Select one of the radio buttons:
• Off: Disable automatic calibration.
• Auto: Calibration is automatically carried out when needed.
• Auto (~10 min): Calibration is automatically carried out approximately every 10
minutes.
• Auto (~30 min): Calibration is automatically carried out approximately every 30
minutes.
• Auto (~60 min): Calibration is automatically carried out approximately every 60
minutes.
3. While the automatic calibration is in progress, the text Calibrating... is displayed
under the image on the screen.
