11.4.12 High dynamic range mode (MF-131B/C only)
The CMOS sensor of the MF-131 offers a special mode by which various nonlinearity points, the
so-called knee-points, can be freely adjusted. This enables the high dynamic range of the sensor
to be compressed into 8 Bit, preserving interesting details of the image. This mode is also known
as multiple slope (dual slope).
