Level features.
BlackLevel 0.000 100.000 - -
Controls the analog
black level as an
absolute physical value.
This represents a DC
offset applied to the
video signal.
BlackLevelAuto - - -
Off,
Continuous
Controls the mode for
automatic black level
adjustment. The exact
algorithm used to
implement this
adjustment is
device-specific.
Off: Analog black level is
user controlled using
BlackLevel.
Continuous: Analog
black level is constantly
adjusted by the device.
BalanceRatioSelector - - -
Red,
Blue
Selects which Balance
ratio to control.
Red: Balance Ratio will
be applied to the red
channel.
Blue: Balance Ratio will
be applied to the blue
channel.
BalanceRatio 0.063 16.000 - -
Controls ratio of the
selected color
component to a
reference color
component. It is used for
white balancing.
BalanceWhiteAuto - - - Off,
Once,
Continuous
Controls the mode for
automatic white
balancing between the
color channels. The
white balancing ratios
are automatically
adjusted.
Off: White balancing is
user controlled using
BalanceRatioSelector
and BalanceRatio.
Once: White balancing is
automatically adjusted
once by the device.
Once it has converged, it
