Willard Boyle and George Smith shared the 2009 Nobel Prize in physics for their work in the invention of the charge-coupled device (CCD). A CCD captures light and converts it into an electric signal, which can then be used to produce an image. CCD’s serve as the primary element in most digital cameras.
