Digital Imaging Services and Digital Imaging Companies - TAWPI
Digital imaging or digital image acquisition is the creation of digital images, typically from a physical object. The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images.
A digital image may be created directly from a physical scene by a camera or similar device. Alternatively, a company may obtain it from another image in an analog medium, such as photographs, photographic film, or printed-paper, by a scanner or similar device or services. Many technical images—such as those acquired with tomographic equipment, side-looking radar, or radio telescopes—are actually obtained by complex processing of non-image data.
Digital image authentication is an emerging issue for companies and producers of high-resolution digital images or services such as health care organizations, law enforcement agencies and insurance companies. There is currently no method available to analyze a digital image and determine if it has been altered or not. However, there are some technologies and services on the horizon which are useful in confirming the non-alteration of digital images whose original producer is known.
Advantages of Digital Imaging
- Digital images will not deteriorate physically or chemically over time.
- Digital imaging permits identical reproduction quality from copy to copy and from generation to generation.
- Images from digital imaging are easily linked to textual descriptions and catalog records.
