Digital imaging or digital image acquisition is the creation of a digitally encoded representation of the visual characteristics of an object,[1] such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability make copies and copies of copies digitally indefinitely without any loss of image quality.
