IID_IuEyeAutoFocus

This interface provides special functions for automatic focusing of the uEye camera that are not covered by the DirectShow standard. To use the interface, you must integrate the uEyeCaptureInterface.h header file into your project.

hint_info

These functions are only supported by the uEye LE USB 3.1 Gen 1 AF.

IuEyeAutoFocus provides the following functions:

AutoFocus_GetAOI	Returns the set focus AOI for the autofocus.
AutoFocus_SetAOI	Sets the focus AOI for the autofocus.
AutoFocus_GetAOISizeMin	Returns the minimum focus AOI for the autofocus.
AutoFocus_SetAOIPreset	Sets a predefined set of supported focus AOI.
AutoFocus_GetNumberOfSupportedAOIs	Returns the number of supported focus AOIs.
AutoFocus_GetHysteresis	Returns the hysteresis value ("search accuracy").
AutoFocus_GetHysteresisDefault	Returns the default hysteresis value ("search accuracy").
AutoFocus_SetHysteresis	Sets the hysteresis value ("search accuracy").
AutoFocus_GetLensResponseTime	Returns the response time of the lens (positioning time) in milliseconds.
AutoFocus_GetLensResponseTimeDefault	Returns the default response time of the lens (positioning time) in milliseconds.
AutoFocus_SetLensResponseTime	Sets the response time of the lens (positioning time) in milliseconds.
AutoFocus_GetLimit	Returns the minimum and maximum limit for the focus search range.
AutoFocus_GetLimitDefault	Returns the minimum and maximum limit for the default focus search range.
AutoFocus_SetLimit	Sets the minimum and maximum limit for the focus search range.
AutoFocus_GetOncePeakSearchAlgorithm	Returns the set peak search algorithm for the autofocus.
AutoFocus_GetOncePeakSearchAlgorithmDefault	Returns the default peak search algorithm for the autofocus.
AutoFocus_GetOnceSupportedPeakSearchAlgorithms	Returns the peak search algorithms supported by the camera for the autofocus.
AutoFocus_SetOncePeakSearchAlgorithm	Sets the peak search algorithm for the autofocus.
AutoFocus_GetSharpnessCalculationAlgorithm	Returns the set algorithm for sharpness calculation of the autofocus.
AutoFocus_GetSharpnessCalculationAlgorithmDefault	Returns the default algorithm for sharpness calculation of the autofocus.
AutoFocus_GetSupportedSharpnessCalculationAlgorithms	Returns the algorithms for sharpness calculation of the autofocus supported by the camera.
AutoFocus_SetSharpnessCalculationAlgorithm	Sets the algorithm for sharpness calculation of the autofocus.
