Parameter	Description
pCapture	Pointer to an IltmmCapture interface.

Returns

S_OK	The function was successful.

Comments

This function will capture a single automation picture.

If the method succeeds, the caller must free the returned picture by calling the interface's Release method.

The frame is captured from the position indicated by the StillTap property.

When capturing from the still pin, the capture happens when the user presses the hardware button for capturing the still image.
If there is not a hardware button or the user doesn't press it, the capture occurs after the timeout specified by the CaptureStillDelay property.

When not capturing from the still pin, the capture occurs after the amount of time specified by the CaptureStillDelay property.
