6.1.6. Knee function

Only in M2CL.

The knee functions can compress the signals in the highlighted areas. The slope over the knee
point is only 20%. The Knee point can be adjusted from 712 to 1023. Knee point at max (1023) is
the same as knee function off. With the knee at 890, the camera can reproduce scene highlight
up to 175%. The image contrast is reduced to 20% for scene luminance higher than the knee
point.

This function can be used in applications where the scene brightness is divided in an area in
shadow, and another in bright sunshine.
