Gray Value Adjustment Damping

The gray value adjustment damping controls the rate by which pixel gray values are changed when
Exposure Auto or Gain Auto or both are enabled.
If an adjustment damping factor is used, the gray value target value is not immediately reached, but
after a certain delay. This can be useful, for example, when objects move into the camera's view
area and where the light conditions are gradually changing due to the moving objects.
By default, the gray value adjustment damping is set to 0.75. This is a setting where the damping
control is as stable and quick as possible.
Setting the Adjustment Damping
The adjustment damping is determined by the value of the GrayValueAdjustmentDampingAbs
parameter.
The higher the value, the lower the adjustment damping is, i.e.
the sooner the target value will be reached,

the adaptation is realized over a smaller number of line acquisitions.

You can set the gray value adjustment damping from within your application software by using the
pylon API. The following code snippets illustrate using the API to set the gray value adjustment
damping:
camera.GrayValueAdjustmentDampingAbs.SetValue(0.5);
You can also use the Basler pylon Viewer application to easily set the parameters.
