Step 6. In the Calibration FPN feature, click the Press… command to perform the calibration.
Step 7. If required, verify the Optical Black Reference Calibration Offset setting; set the FPN
Correction Mode to Off and Black Level to 0.
Grab an image and use a histogram to verify that pixel values are above zero; if necessary, adjust
the Optical Black Reference Calibration Offset. Higher offset values may be required when the
camera is operating at very high temperature and frame rates. Set the FPN Correction Mode to
Calibration and use the Calibration FPN command to recalculate the calibration and adjust the
offset until the result is satisfactory.
Step 8. If the calibration is satisfactory, in the Save FPN Calibration feature click the
Press… command to save the calibration to the selected user set.
For each gain setting required perform and save the calibration; coefficients for each gain setting
are saved in the user set (gain settings for which no calibration is done use default coefficients).
Step 9. To load this user set when resetting or powering on the camera, use the Power-up
Configuration dialog. Click Setting… Power-up Configuration feature, in Camera Information
category.
In the Power-up Configuration dialog box select the required user set both Camera Power-up
configuration and Load / Save configuration and click Save.
This ensures that the camera loads the saved parameters the next time the camera is turned on.
