7.7 Disable Parameter Limits
For each camera parameter, the allowed range of parameter values is normally limited. 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 disable parameter limits feature lets you disable the factory parameter limits for certain
parameters. When the factory parameter limits are disabled, 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.
Disabling Parameter Limits Using Basler pylon
Disabling the limits for a parameter using Basler pylon is a two step process:
 Use the Parameter Selector to select the parameter whose limits you wish to disable.
 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 );
// Disable the factory limits for the selected parameter (Gain)
Camera.RemoveLimits.SetValue( true );
// Select the Black Level parameter
Camera.ParameterSelector.SetValue( ParameterSelector_BlackLevel );
// Disable the factory limits for the selected parameter (Black Level)
Camera.RemoveLimits.SetValue( true );
// Select the Exposure Time parameter
Camera.ParameterSelector.SetValue( ParameterSelector_ExposureTime );
// Disable the factory limits for the selected feature (Exposure Time)
Camera.RemoveLimits.SetValue( true );
You can also use the Basler pylon Viewer application to easily set the parameters. Note that the
disable 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 4 on page 45.
Currently, the parameter limits can only be disabled on the Gain, the Black Level,
and the Exposure Time features.
