One can conclude here that a good color tracking can only be met by using three previously (input) balanced
color signals
Analog Digital Conversion
The analog color signals must pass through an Analog/Digital conversion circuit prior to any digital processing 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 is not optimally used.

White balance : In the projector, we will set the contrast for each color until we get a 100% light output picture when projecting a
100% white image (image A)
Black balance : In the projector, we will set the brightness for each color until we get a 0% light output picture when projecting a
100% black image (image B).
The changeover from min to max is indicated by the apparition of bright spots also called “digital noise”

8.8.3 Input balance for YPrPb signals
Remark on the input balance of a component video source
Before starting the Input Balance procedure, generate a signal with dominant white parts.
Input balance is also available for a component video source under following conditions:
• A component video signal...

• The white balance happens only on Green.
Adjust until bright spots appear in the image.

• The black balance happens on the three colors.
The PR and PB connector have to be removed from the input.
Adjust until noise appears in the image.

8.9 AGC on Video
AGC
Automatic Gain Control: allows an automatic amplitude (gain) control of the incoming video signal
AGC is only for Video signals.
Enabling/disabling the AGC
1. PressMENUto activate the menu bar.

The AGC can be disturbing in case of Macrovision encoded signals, therefore the AGC can be disabled (OFF)
at any time
8.10 Manual Gain Control
What can be done ?
WhenAGC on Videois disabled, the gain of the incoming video signal can be set manually. The manual gain control must be done
on an external pattern with white areas (grey scale bar pattern).
How to set the Manual Gain Control ?
1. PressMENUto activate the menu bar.
