The IAMCameraControl interface provides local or remote control over a camera. Applications can use this interface to control camera settings such as zoom, pan, aperture adjustment, or shutter speed. To obtain this interface, query the filter that controls the camera.
In addition to the methods inherited from IUnknown, the IAMCameraControl interface exposes the following methods.
|Get||Retrieves the current setting of a camera property.|
|GetRange||retrieves the range and default value of a specified camera property.|
|Set||Sets a specified property on the camera.|
For Windows Driver Model (WDM) devices, the WDM Video Capture Filter automatically exposes this interface if the WDM driver supports the PROPSETID_VIDCAP_CAMERACONTROL property set. For more information, see the Windows DDK documenation.
