Achieving a good image15
Calibration is needed whenever the output image becomes spatially noisy. The output
can become spatially noisy when the ambient temperature changes (such as from day to
night operation, and vice versa).
The calibration is carried out automatically when needed. It is also possible to perform a
calibration manually.
While the calibration is in progress, the text Calibrating... is displayed.
