Gamma
The transfer characteristics of most cameras and displays are nonlinear. For a display, a small change in amplitude
when the signal level is small produces a change in the display brightness level, but the same change in amplitude at a
high level will not produce the same magnitude of brightness change. This nonlinearity is known as gamma. Different
gamma curves are available to compensate the nonlinearity.

6.4.6.1 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 6-4 , we are
quite sure that the amplitude of these color signals is subject to alterations.
An example of alteration may be a DC component added to the signal, in the form of a DC...

Black level setting : brightness
White level setting : contrast
The same absolute black and white level for the three colors allows the same reference for Brightness and Contrast control of the
picture !
These two references also set the range in which the ADC will work for that particular source (this explains also why each input
balance setting is linked to a particular source and thus saved in the imagefile).
