'''Digital imaging''' or '''digital image acquisition''' is the creation of [[Digital image|digital images]], such as of a physical scene or of the interior structure of an object.

== Description ==

The term is often assumed to imply or include the [[Data processing|processing]], compression, storage, printing, and display of such [[Image|images]].  See [[Data (computing)]].

Digital imaging can be classified by the type of [[electromagnetic radiation]] or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. 

In all classes of digital imaging, the information is converted by image sensors into digital signals that are [[processed]] by a [[computer]] and [[Output (computing)|outputted]] as a [[visible-light]] [[image]].

== Examples ==

* The medium of [[visible light]] allows [[digital photography]] (including digital videography) with various kinds of digital cameras (including digital video cameras). 

* X-rays allow digital X-ray imaging (digital radiography, fluoroscopy, and CT), and gamma rays allow digital gamma ray imaging (digital scintigraphy, SPECT, and PET). 

* Sound allows ultrasonography (such as medical ultrasonography) and sonar, and radio waves allow radar. 

Digital imaging lends itself well to image analysis by [[software]], as well as to [[image editing]] (including [[Photo manipulation|image manipulation]]).
