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. 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.
