Rapid Scan of images from text books. camera? hand-held scanner? - diagrams of a digital camera

I am a student. What is the best way to scan multiple images from books, to continue with my lecture notes. My scanner takes forever, is there a faster way? I could spend a few hundred dollars for a sloution that quickly and easily. Usually not necessary to scan the entire page, only the diagrams. I have tried my digital camera for this use, but there is no blurY and legeable.
