10.2 Remove Parameter Limits

For each camera feature, the allowed range of any associated 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 remove parameter limits feature lets you remove the factory limits for parameters associated

with certain camera features. When the factory 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.

The values for any extended limits can be determined by using the Basler pylon Viewer or from

within your application via the pylon API.

Currently, the limits can only be removed from these features and parameters:

 Digital Gain: Removing the parameter limits on the digital gain feature will only remove the

lower limit. The lower limit for the DigitalGain parameter is reduced to 0.

For more information about the digital gain feature, see Section 10.1 on page 163.

 ExposureOverhead parameter; for more information, see Section 8.5.1 on page 138.

Removing Parameter Limits

To remove the limits for a parameter:

 Use the Parameter Selector to select the parameter whose limits you want to remove.

 Set the value of the Remove Limits parameter.

You can set the Parameter Selector and the value of the Remove Limits parameter from within your

application software by using the Basler pylon API. The following code snippet illustrates using the

API to set the selector for digital gain and the parameter value:

// Select the feature whose factory limits will be removed.

Camera.ParameterSelector.SetValue( ParameterSelector_Gain );

// Remove the limits for the selected feature.

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.
