DIGITAL IMAGE Definition
A Digital Image is taken with a digital camera, which uses a process where
pictures are taken to a computer disk or memory card rather than film. The image is
focused on a computer chip inside the camera and is instantly converted to an image that
you can see on the screen on the back of your camera. Digital cameras can take pictures
more accurately. Film cameras have good electronics to control the camera, but the
computers inside film cameras have to "guess" what light the film will be
exposed to. In a digital camera the CCD element allows the camera to actually
"see" the picture before it take it. Because the camera can see the picture, the
computer inside can more accurately adjust the electronics to take the best picture
possible. This leads to much clearer, crisper final images than print film which must be
scanned for use on a PC.
