value.
The contrast can be adjusted between 0 and 255 in steps of 1 or
10. Select ’Full’ to set the contrast immediately to 255 and select

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.
