How to take a capture with the webcam?

I'm trying to capture a video that I get directly from the web, but at the moment of checking the capture I realize that this is not in the real colors, if not in green or blue, I want to know how to correct this error The code I use is the following:

    vid=videoinput('winvideo');
    start(vid);
    picture=getdata(vid,1);
    preview(vid)
    imaqmontage(picture);

the stored image is
