The IAMVideoProcAmp interface enables an application to adjust the qualities of an incoming video signal, such as brightness, contrast, hue, saturation, gamma, and sharpness.
The WDM Video Capture filter exposes this interface if the hardware supports image adjustment.
In addition to the methods inherited from IUnknown, the IAMVideoProcAmp interface exposes the following methods.
| Method | Description |
| GetRange | Retrieves minimum, maximum, and default values for setting properties. |
| Set | Sets video quality for a specified property. |
| Get | Retrieves video quality for a specified property. |
Remarks
For Windows Driver Model (WDM) devices, the WDM Video Capture Filter automatically exposes this interface if the WDM driver supports the PROPSETID_VIDCAP_VIDEOPROCAMP property set. For more information, see the Windows DDK documenation.
