uEye DirectShow 4.97

IID_IuEyePhotometry

This interface provides special functions for controlling the automatic image control on some uEye models that are not covered by the DirectShow standard. Photometric settings can be used for the automatic image control to select certain measurement fields or image areas that are then used to determine the correct exposure time and gain settings. To use the interface, you must integrate the uEyeCaptureInterface.h header file into your project.

IuEyePhotometry provides the following functions:

Photometry_IsAutoGainSupported

Returns information on whether the sensor supports automatic gain.

Photometry_IsAutoGainEnabled

Returns information on whether automatic gain is enabled.

Photometry_AutoGainEnable

Enables automatic gain.

Photometry_GetAutoGainMode

Returns the set measurement field mode for the automatic gain.

Photometry_SetAutoGainMode

Sets the measurement field mode for the automatic gain.

Photometry_GetDefaultAutoGainMode

Returns the default mode for the automatic gain.

Photometry_GetSupportedAutoGainModes

Returns the supported measurement field modes for the automatic gain.

Photometry_IsAutoShutterSupported

Returns whether the sensor supports automatic exposure time.

Photometry_IsAutoShutterEnabled
