5-3-5. LEVEL DEPENDENT control

To avoid appearance of noise component in dark areas, detail signal at these levels are
suppressed. This control adjusts detail signal level in the area.

5-3-6. KNEE APE control

When compressing highlight portions with KNEE control due to overexposed image (blown-out
highlights), detail signals will also be compressed and may cause softening in highlight areas.
This can be compensated by using KNEE APE LEVEL control.
