Recalibration offset
An existing calibration file must be loaded on Xeneth in order to proceed with the recalibration
offset procedure. As mentioned earlier in Section 6.3 recalibration offset modifies the FPN
calibration but does not change the PRNU calibration. Therefore, it is only suitable for minor
changes which does not affect the PRNU of the camera.
Load a file with the required analogue gain factor.
Disable the calibration file in order to make the necessary changes. We recommend limiting
the modification to exposure time only.
Unselect “Enable image correction” to disable the calibration file.
