Automatic FPN Calibration
The camera can optionally be configured to automatically recalibrate the FPN
correction, depending on the value of autoShutterMode:
-
Off: the camera will never trigger a FPN calibration on its own; this is the only
available option when using an external shutter target.
-
Temperature: the camera will trigger a FPN recalibration if its internal
temperature drifts more than autoShutterMaxTempDiff Celsius since the last FPN
calibration;
-
Time: the camera will trigger a FPN recalibration if more than
autoShutterMaxDelay seconds have elapsed since the last FPN calibration;
-
TimeTemperature: FPN recalibration will be triggered if either the temperature or
time criteria is exceeded.
The autoShutterMinDelay feature allows setting a minimum time between automatic
FPN calibrations.
If the camera is not actively acquiring images and a FPN correction is due for
recalibration, flatfieldCalibrationStatus will switch to CalibrationPending; the next time
acquisition starts, the camera will first run the FPN calibration then start outputting
images.
