Remove Parameter Limits#

The Remove Parameter Limits camera feature allows you to remove the factory limits of certain camera features.

When the factory limits are removed, extended parameter value ranges are available.

Using the Feature#

How It Works#

Normally, a parameter's allowed value range is limited. These factory limits are designed to ensure optimum camera performance and, in particular, good image quality. For certain use cases, however, you may want to specify parameter values outside of the factory limits. This is where the ability to remove parameter limits comes in useful.

Which parameter limits can be removed depends on your camera model.

Removing a Parameter Limit#

To remove a parameter limit:

  1. Select the parameter whose limits you want to remove in the RemoveParameterLimitSelector.
  2. Set the RemoveParameterLimit parameter to true.

Specifics#

Info

The following table lists the parameter limits that can be selected using the RemoveParameterLimitSelector. However, there are parameters whose limits remain unchanged. Make sure that the parameter limit has been effectively removed by checking the corresponding parameter, e.g., Gain.

  1. Beyond the Gain parameter's factory limits, digital gain will be added to the analog gain.

  2. Removing this parameter limit will increase the camera's maximum frame rate. You may see some degradation in the overall image quality. In many applications, however, the benefits of an increase in the maximum allowed frame rate will outweigh the drawbacks of a marginal decrease in image quality.

You can also use the pylon Viewer to easily set the parameters.
