메소드	설명
ConfigureCapture ( ) : void	We can configure some settings related to capturing images from the camera. Primarily we want to control how many buffers are used in the capture process. If we are doing continuous capture, we can configure the interval between subsequent frames.
GetBitmapInfo ( ) : BITMAPINFO
GrabSingleFrame ( ) : bool	Grab a single frame from the video device. Disables Overlay and preview. Since we want complete control of video grabbing, this is what we want. We don't want or need a preview window, and we don't want to be doing overlay either. As the frame is grabbed, our frameDelegate function is called with the retrieved frame.
