Saving Fixed Pattern Noise Calibration

After calibration, the FPN calibration coefficients can be saved to non-volatile camera
memory. When enabled, the FPN correction is applied in addition to the default factory
calibrated non-uniformity correction.
FPN Compensation Mode = Off
Note: FPN correction is only valid at the operating temperature at which
it was calculated; the further the camera operating temperature is from
the correction point, the less accurate the correction.

Performing Manual FPN Correction with Internal Shutter

1. Set the FPN Target Mode feature to
FPN Correction category:
2. With the camera at nominal operating temperature, execute the calibration using
the Calibrate FPN Compensation feature:
3. If the FPN results are satisfactory, coefficients can be saved to non-volatile
device memory using the Save FPN Calibration (flatfieldCalibrationSave) feature:
