8.6.9 Input balance
8.6.9.1 Introduction to Input Balance
Introduction: Unbalanced color signals
When transporting signals, there is always a risk of deterioration of the information contained in the signals.
In case of information contained in the amplitude of the signals which is the case of data color signals (R,
G, B),image 8-25 , we are quite sure that the amplitude of these color signals is subject to alterations.
An...

One can conclude here that a good color tracking can only be met by using three previ-
ously (input) balanced color signals
Analog Digital Conversion
The analog color signals must pass through an Analog/Digital conversion circuit prior to any digital pro-
cessing in the PMP.
A typical ADC transforms the analog value into an 8 bit coded digital signal.
The graphic shows that when converting a signal containing a DC offset component the range of the
converter...

The changeover from min to max is indicated by the apparition of bright spots also called
“digital noise”

4. Select White balance blue and adjust the blue white level (gain) on a minimal value.
Note:This minimal value is not necessary , provided that the 2 other colors are not influencing too
much the color to be adjusted, in fact the aim is to minimize the effect of the two other colors
since there is a risk of reaching too soon the transition (bright spots) due to the contribution of
these two other colors signals.
