Host-based Flat-Field Correction With Calibration AOI
In some cases it might be necessary to use just a specific area within the camera's field of view to calculate the
correction values. In this case just a specific AOI will be used to calculate the correction factor.
You can set the
"host-based flat field correction"
in the following way:
1. All necessary setting can be found under
"ImageProcessing"-
>
"FlatfieldFilter"
.
2. Stop
"Continuous"
acquisition mode.
3. Set
"CalibrationImageCount"
to, for example, 5.
4. Set
"Mode"
to "Calibrate".
5. Set
"CalibrationAoiMode"
to "UseAoi".
6. Set the properties (
"X, Y and W, H"
) appeared under
"CalibrationAOI"
to the desired AOI.
7. Start
"Continuous"
acquisition mode.
8. Finally, you have to activate the correction: Set the
"Mode"
to "On".
