title: Capturing Webcam Image without preview view or cameraUI?
body: <p>I'm developing a windows UI C# app and I'm attempting to Capture a webcam image without using the <code>CameraCaptureUI</code>, as I don't want any interruptions in my app.</p>
  
  <p>I am using signatures on a canvas, and I want to capture an image of the user's face when he begins his signature to verify identities without altering the screen.</p>
  
  <p>How might I accomplish this?</p>
