Using Flat Field Correction
From the CamExpert menu bar enable Flat Field correction (
Pre-Processing • Flat Field Correction • Hardware
).
Now when doing a live grab or snap, the incoming image is corrected by the current flat field calibration data for
each pixel.
Use the menu function
Tools • Flat Field Correction • Load
to load in a flat field correction image from
previously saved calibration data. CamExpert allows saving and loading calibration data for all cameras used with
the imaging system.
