    Cheese is a program that takes image from web camera..
    The moment that is supposed to take the picture it makes the screen be white for 1 sec and at that second it takes the picture..

      Show a fullscreen, nondecorated, always on top, white widget --- probably you need to hack it a bit, but that's the idea.
