High dynamic range mode

(MARLIN F-131B/C only)

The CMOS sensor of the MARLIN F-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 mul-

tiple slope (dual slope).
