KNEE SATURATION

When a camera's KNEE function is set to ON, the bright areas of the image are compressed in the KNEE circuit. In this proces, both the luminance (Y) signals and color-difference (R-Y, B-Y) signals are compressed together, which can sometimes cause the color saturation of the image to drop.

KNEE SATURATION is a function that eliminates this saturation drop while maintaining the original function of the KNEE circuit. When KNEE SATURATION is set to ON, the color-difference (R-Y, B-Y) signals are sent to the KNEE SATURATION circuit which applies a knee function optimized for these color signals. These signals are then added back to the mainstream signals, obtaining the final output signal.
The levels of color vividness (KNEE SAT LEVEL) can be adjusted in the range of -99 to +99.

***KNEE: A function that allows contrast to be reproduced in the bright areas of objects within the video signal's dynamic range (the range of teh luminance that can be processed).
