Basler racer Camera Link 106

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 following limits can be removed:

 Gain: Removing this parameter limit reduces the lower limit for the Gain parameter to 0. For

more information, see Section 8.2.1 on page 102.

 Target Gray Value: Removing this parameter limit increases the lower and upper limits of the

TargetGrayValue parameter used for auto functions. For more information, see Section 8.5 on

page 110.

 Exposure Overhead: Removing this parameter limit allows you to improve line acquisition.

Also, it slightly increases the upper limit of the ExposureOverlapTimeMaxAbs parameter. For

more information, see Section 6.3.3 on page 82, and Section 6.4.2 on page 91.

 Exposure Overlap Time Max: Removing this parameter limit greatly increases the upper limit

of the ExposureOverlapTimeMaxAbs parameter. For more information, see Section 6.1.5.2 on

page 65, Section 6.2.1.2 on page 75, and Section 6.3.3 on page 82.

1. Use the ParameterSelector parameter to select the parameter whose limits you want to

remove.

2. Set the RemoveLimits parameter to True.

You can set the ParameterSelector and the RemoveLimits parameter values from within your

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

API to set the parameter values:

// Select the parameter 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.

To remove the limits for a parameter using Basler pylon:
