Try a nested loop.

Check every 10 or 100 or so pixels accross, loop this going down the image, so you scan a matrix.

I think picture1.point will return the pixel colour.

Check if it has changed more than a certain amount. checking for any change at all may be over-sensitive, especially if it's something like a webcam.
