Configuration of the camera
High dynamic range mode
(Marlin F-131B only)
The CMOS sensor of the Marlin F-131 offers a special mode by which various non-
linearity 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).
