Black Level

Adjusting the camera's black level will result in an offset to the pixel values output from the camera.
The camera's black level is determined by the BlackLevelRaw parameter with the black Level
selector set to All. All pixels in the sensor are affected by this setting.
If the camera is set for a pixel format with an 8 bit depth, an increase of 16 in a black level setting
will result in a positive offset of 1 in the pixel values output from the camera. And a decrease of 16
in a black level setting will result in a negative offset of 1 in the pixel values output from the camera.
If the camera is set for a pixel format with a 12 bit depth, an increase of 1 in a black level setting will
result in a positive offset of 1 in the pixel values output from the camera. A decrease of 1 in a black
level setting will result in a negative offset of 1 in the pixel values output from the camera.
To set the black level using Basler pylon:
1. Set the BlackLevelSelector parameter to All.
2. Set the BlackLevelRaw parameter to your desired value.
You can set the BlackLevelSelector and the BlackLevelRaw parameter values from within your
application software by using the pylon API. The following code snippet illustrates using the API to
set the parameter values:
// Set BlackLevelRaw All
camera.BlackLevelSelector.SetValue(BlackLevelSelector_All);
camera.BlackLevelRaw.SetValue(64);
For detailed information about using the pylon API, refer to the Basler pylon Programmer's Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on
To set the black level via direct register access:
Set the value of the Black Level All register.
