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.

Sample Code#

ace Classic/U/L GigE Cameras#

// Select the Gain parameter
camera.ParameterSelector.SetValue(ParameterSelector_Gain);
// Remove the limits of the selected parameter
camera.RemoveLimits.SetValue(true);

INodeMap& nodemap = camera.GetNodeMap();
// Select the Gain parameter
CEnumParameter(nodemap, "ParameterSelector").SetValue("Gain");
// Remove the limits of the selected parameter
CBooleanParameter(nodemap, "RemoveLimits").SetValue(true);

// Select the Gain parameter
camera.Parameters[PLCamera.ParameterSelector].SetValue(PLCamera.ParameterSelector.Gain);
// Remove the limits of the selected parameter
camera.Parameters[PLCamera.RemoveLimits].SetValue(true);

/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Select the Gain parameter */
errRes = PylonDeviceFeatureFromString(hdev, "ParameterSelector", "Gain");
CHECK(errRes);
/* Remove the limits of the selected parameter */
errRes = PylonDeviceSetBooleanFeature(hdev, "RemoveLimits", 1);
CHECK(errRes);

# Select the Gain parameter
camera.ParameterSelector.Value = "Gain"
# Remove the limits of the selected parameter
camera.RemoveLimits.Value = True

Other Cameras#

// Select the Gain parameter
camera.RemoveParameterLimitSelector.SetValue(RemoveParameterLimitSelector_Gain);
// Remove the limits of the selected parameter
camera.RemoveParameterLimit.SetValue(true);

INodeMap& nodemap = camera.GetNodeMap();
// Select the Gain parameter
CEnumParameter(nodemap, "RemoveParameterLimitSelector").SetValue("Gain");
// Remove the limits of the selected parameter
CBooleanParameter(nodemap, "RemoveParameterLimit").SetValue(true);

// Select the Gain parameter
camera.Parameters[PLCamera.RemoveParameterLimitSelector].SetValue(PLCamera.RemoveParameterLimitSelector.Gain);
// Remove the limits of the selected parameter
camera.Parameters[PLCamera.RemoveParameterLimit].SetValue(true);

/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Select the Gain parameter */
errRes = PylonDeviceFeatureFromString(hdev, "RemoveParameterLimitSelector", "Gain");
CHECK(errRes);
/* Remove the limits of the selected parameter */
errRes = PylonDeviceSetBooleanFeature(hdev, "RemoveParameterLimit", 1);
CHECK(errRes);

# Select the Gain parameter
camera.RemoveParameterLimitSelector.Value = "Gain"
# Remove the limits of the selected parameter
camera.RemoveParameterLimit.Value = True

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