snapshot from webcam-stream

    hi everybody!
    i use jit.qt.grab for grabbing a webcam-stream.
    what i would like to do, is taking a single frame (snapshot) out of the stream when clicking a button.
    i'd like to use this snapshot as basis for creating a difference image to the live webcam-stream.
    can anybody please tell me which object i have to use for taking the snapshot out of the stream?
    thanks,
    nic
