Setting the Black Level
When the camera is set for four tap digitization mode, setting the black level with Basler pylon is a
several step process:
To set the Black Level All parameter value:
 Set the Black Level Selector to All.
 Set the Black Level Raw parameter to your desired value.
To set the Black Level Tap 1, Black Level Tap 2, Black Level Tap 3, or Black Level Tap 4 parameter
value:
 Set the Black Level Selector to Tap 1, Tap 2, Tap 3, or Tap 4.
 Set the Black Level Raw parameter to your desired value.
You can use the pylon API to set the Black Level Selector and the Black Level Raw parameter
values from within your application software. The following code snippet illustrates using the API to
set the selector and the parameter value:
// Set Black Level All
Camera.BlackLevelSelector.SetValue ( BlackLevelSelector_All );
Camera.BlackLevelRaw.SetValue( 64 );
// Set Black Level Raw Tap 1
Camera.BlackLevelSelector.SetValue ( BlackLevelSelector_Tap1 );
Camera.BlackLevelRaw.SetValue( 0 );
// Set Black Level Raw Tap 2
Camera.BlackLevelSelector.SetValue ( BlackLevelSelector_Tap2 );
Camera.BlackLevelRaw.SetValue( 0 );
// Set Black Level Raw Tap 3
Camera.BlackLevelSelector.SetValue ( BlackLevelSelector_Tap3 );
Camera.BlackLevelRaw.SetValue( 0 );
// Set Black Level Raw Tap 4
Camera.BlackLevelSelector.SetValue ( BlackLevelSelector_Tap4 );
Camera.BlackLevelRaw.SetValue( 0 );
For normal operation, we recommend that you set the value of the tap black levels
to zero and that you simply use Black Level All to set the black level. Typically, the
tap black level settings are only used if you want to adjust the black level balance
between the quadrants of the sensor.
