Y processing
The separate Y processing (see Fig.5) includes the
following features:
Saturation concealment to reduce the typical saturation
distortion
Contour processing to improve picture sharpness
Noise reduction
Black offset
Pre-gaincontroltoadjust theY signalwith respecttothe
gamma range
Knee function (compression factor and knee point are
adjustable)
Adjustable gamma function
Gain control.

8.5
RGB to UV conversion
After R, G and B processing, the data path is converted to
U and V signals (see Fig.1). As a result of the reduced
bandwidth, the Y signal is only used as an input for control
loop purposes (measurement engine).
8.6
UV processing
The chrominance processing consists of a noise reduction
by coring and the UV gain control.
8.7
Display function
As an optional feature and for software debugging, it is
possible to visualize:
Eight display bars (assigned via the microcontroller)
Several measurement engine inputs.
