Flat Field Correction Calibration

Flat Field Correction Calibration (FFC) contains FPN (Fixed Pattern Noise) and PRNU (Photon

Response non-uniformity) corrections.

Note: Before performing a FFC, we recommend you evaluate the “bare image” characteristics,

which determine the quality of FFC, applied to the image.

To obtain a bare image, disable FPN and PRNU coefficients:

• Choose Off from Flat Field Correction Mode.
