Adjusting The Knee Saturation - Sony BVP-900 Series System Manual

4-9-3 Adjusting the Knee Saturation

If the skin tone seems yellowish or some colors are lost
with normal knee control, such problems may be
eliminated using the knee saturation function.
This function compresses (applies knee to) the
luminance (Y) and saturation while maintaining the
hue when the luminance exceeds the knee point.
The controls assigned for knee saturation level allow
you to adjust the compression for the saturation.
To turn on the knee saturation function
Press and light the KNEE SAT button of the MSU-
700A or the RCP-730/731.
You can also turn on/off the knee saturation function
on the adjustment display of the menu operation block.
