IDS peak 2.8.0 / uEye+ firmware 3.33

Sets the automatic exposure control when ExposureMode is "Timed". Neither AcquisitionFrameRate nor Gain settings are changed. ExposureAuto can be combined with GainAuto.

Values description

•Off: Exposure duration is user controlled using ExposureTime.

•Once: Exposure duration is adapted once by the camera. Once it has converged, it returns to the "Off" state.

•Continuous: Exposure duration is constantly adapted by the camera to maximize the dynamic range.

Code example

C++

// Determine the current entry of ExposureAuto
std::string value = nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ExposureAuto")->CurrentEntry()->SymbolicValue();
// Get a list of all available entries of ExposureAuto
auto allEntries = nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ExposureAuto")->Entries();
std::vector<std::shared_ptr<peak::core::nodes::EnumerationEntryNode>> availableEntries;
for(const auto & entry : allEntries)
{
  if ((entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotAvailable)
          && (entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotImplemented))
  {
      availableEntries.emplace_back(entry);
  }
}
// Set ExposureAuto to "Off"
nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ExposureAuto")->SetCurrentEntry("Off");

C#

// Determine the current entry of ExposureAuto
string value = nodeMapRemoteDevice.FindNode<peak.core.nodes.EnumerationNode>("ExposureAuto").CurrentEntry().SymbolicValue();
// Get a list of all available entries of ExposureAuto
allEntries = nodeMapRemoteDevice.FindNode<peak.core.nodes.EnumerationNode>("ExposureAuto").Entries();
List<string> availableEntries = new List<string>();
for(int i = 0; i < allEntries.Count(); ++i)
{
  if ((allEntries[i].AccessStatus() != peak.core.nodes.NodeAccessStatus.NotAvailable)
          && (allEntries[i].AccessStatus() != peak.core.nodes.NodeAccessStatus.NotImplemented))
  {
      availableEntries.Add(allEntries[i].SymbolicValue());
  }
}
// Set ExposureAuto to "Off"
nodeMapRemoteDevice.FindNode<peak.core.nodes.EnumerationNode>("ExposureAuto").SetCurrentEntry("Off");

Python
