Panasonic AJ-PX230 - KNEE APE Control; White Clip

Concept of detail compensation for highlight areas with KNEE APE LEVEL control
3-3. KNEE APE control
When compressing highlight portions with KNEE control to avoid overexposed image (blown-out highlights), detail signal
will also be compressed and it may cause softening in highlight areas. This can be compensated by using KNEE APE
LEVEL control.
