ABSTRACT
In contrast, a digital camera utilizes a charge-coupled device (CCD) in place of film. A CCD is a silicon chip composed of individual pixels that transform light into voltage in a manner similar to the transformation of chemical emulsions into silver grains on film [5]. A computer within the camera converts this voltage into binary data as a series of ones and zeroes. These discrete binary units provide the fundamental difference between a digital image and the continuous spectrum of values of an analog signal.
