Charge-coupled device (CCD)

Summary: At the back of a digital camera (see This is called a charge-coupled device (CCD). When light hits each pixel, it produces a charge. The light produces an electrical, not chemical, effect. When you take a picture, this charge is moved off each of the pixels and stored. This is why there is a slight delay (short wait) before you can take another picture.
