Note:
Repeating the defective pixel corrections will accumulate the correction data which leads to
a higher value in "DefectivePixelsFound". If you want to reset the correction data or
repeat the correction process you have to set the (Filter-) "Mode = Reset Calibration

18.3.1.2 Dark Current Correction
Dark current is a characteristic of image sensors, which means, that image sensors also deliver
signals in total darkness by warmness, for example, which creates charge carriers spontaneously.
This signal overlays the image information. Dark current depends on two circumstances:
exposure time
The longer the exposure, the greater the dark current part. I.e. using long exposure times,
the dark current itself could lead to an overexposed sensor chip
