10.4 Remove Parameter Limits
For each camera parameter, the allowed range of parameter values is normally limited. A parameter
that is outside the allowed parameter range is automatically set to, either the minimum or maximum
value, depending on whether the entered value is below the minimum or above the maximum
allowed value. The factory limits are designed to ensure optimum camera operation and, in
particular, good image quality.
For special camera uses, however, it may be helpful to set parameter values outside of the factory
limits.
The remove parameter limits feature lets you remove the factory parameter limits for certain
parameters. When the factory parameter limits are removed, the parameter values can be set within
extended limits. Typically, the range of the extended limits is dictated by the physical restrictions of
the camera’s electronic devices, such as the absolute limits of the camera’s variable gain control.
Removing the Parameter Limits
Removing the limits for a parameter is a two step process:
Use the Parameter Selector to select the parameter whose limits you wish to remove.
Set the value of the Remove Limits parameter.
You can use the pylon API to set the Parameter Selector and the value of the Remove Limits
parameter from within your application software. The following code snippet illustrates using the API
to set the selector and the parameter value:
// Select the Gain parameter
Camera.ParameterSelector.SetValue( ParameterSelector_Gain );
// Remove the factory limits for the selected parameter (Gain)
Camera.RemoveLimits.SetValue( true );
You can also use the Basler pylon Viewer application to easily set the parameters. Note that the
remove parameter limits feature will only be available at the "guru" viewing level.
For more information about the pylon API and the pylon Viewer, see Section 3 on page 21.
Currently, the parameter limits can only be removed on the gain and the prelines
features.
