solid white image

Question

when pointing a logitech quickcam color out my window, if it's a really sunny day, the image washes out becomes a solid white image. i'm unable to force motion to adjust the brightness levels. if its a really cloudy day or i bring the camera back inside the image is fine. are there any other ways to adjust the iris?
