PRNU Correction
Step 1: Apply illumination and place a white flat target in the location where the real object will be.
Ideally, you would use a professional target. For convenience, you can use white paper as the
target. The result of using paper may produce grain effect — where visible vertical lines show up in
grabbed images.
Two common ways to correct the grain effect are:
1) Target in motion while PRNU Correction is performed.
2) Defocus lens while PRNU Correction is performed.
Select Off from Flat Field Correction Mode drop-down menu and check the bare image line profile.
Step 2: Select Calibration from Flat Field Correction Mode drop-down menu.
Step 3: Adjust the calibration target in the Flat Field Calibration Target (in DN) if necessary.
Note: 200 DN is commonly used target in 8-bit output format.
Step 4: Select 2048 or 4096 from Flat Field Calibration Sample Size drop-down menu.
Step 5: Press the Press… command in Calibrate PRNU menu.
