FPN Correction Using Triggered Acquisition

FPN correction provides the best image quality if FPN calibration is performed under
normal operating conditions. This depends on how the sensor is triggered:
- If TriggerMode is set to Off or the Exposure Alignment Mode (readoutAlignment)
is set to FreeRunning, then the camera is constantly acquiring images from the
sensor. In this configuration no special care is required for FPN calibration.
- If TriggerMode is On and readoutAlignment is set to FrameOnDemand, triggers
should be provided to the camera at the same rate they will be provided in normal
camera operation. If no triggers are provided, the FPN calibration will fail and
flatfieldCalibrationStatus will return Timeout.
