8.3 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 the digital gain feature. 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 8.2.1.2 on page 79.

Removing Parameter Limits Using Basler pylon

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 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.

Removing Parameter Limits Using Direct Register Access

To disable the limits for the Gain parameter using direct register access:

 Set the value of the Remove Param Limits Gain register to enabled.

For more information about direct register access, see Section 3.2 on page 16.
