13.3.1
Signal dynamic range
The M30 imager has an 8-bit signal range, which means that it can deliver 0 - 255 AD
units in linear or multi-slope HDR mode. The sensor contains fixed-pattern noise (FPN)
correction, which removes gradients from the image data. The FPN correction causes
a small reduction of the resulting signal range, and the expected useful signal range is
around 240 AD units.
When the imager is saturated, residual FPN may appear.
