Using Flat Field Correction | Faber M1024, M640, M1600, M1400

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.

Flat Field Correction Control via Sapera LT or GenICam Applications

Sapera

Genie Sapera parameters for Flat Field Correction:

FlatFieldEnable = Enable Flat Field Correction {False=0, True=1} FlatFieldFormat = {RO: mono 8, mono 9, mono 10, RGB} FlatFieldWidth = read buffer width

FlatFieldHeight = read buffer height FlatFieldGainMin = read minimum gain value FlatFieldGainMax = read maximum gain value FlatFieldOffsetMin = read minimum offset value FlatFieldOffsetMax = read maximum offset value FlatFieldGainBuffer = Flat Field correction gain data buffer FlatFieldOffsetBuffer = Flat Field correction offset data buffer

Sapera++ Class constructor: SapFlatField::SapFlatField

In CamExpert, these features are available from the “Pre-Processing” menu.
