Digital imaging will reduce the need for physical contact with original images. [37] Furthermore, digital imaging creates the possibility of reconstructing the visual contents of partially damaged photographs, thus eliminating the potential that the original would be modified or destroyed. [37]
The history of digital photography began in the 1950s. In 1951, the first digital signals were saved to magnetic tape via the first video tape recorder. [3] Six years later, in 1957, the first digital image was produced through a computer by Russell Kirsch. It was an image of his son. [4] First digital image ever created, by Russell Kirsch. It ...
Digital image processing allows the use of much more complex algorithms, and hence, can offer both more sophisticated performance at simple tasks, and the implementation of methods which would be impossible by analogue means. In particular, digital image processing is a concrete application of, and a practical technology based on: Classification

A digital image is an image composed of picture elements, also known as pixels, each with finite, discrete quantities of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with x, y on the x-axis and y-axis, respectively.

View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection; the second is the discovery that some substances are visibly altered by exposure to light.

Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. [1]
Digital single-lens reflex cameras (DSLR) is a camera with a digital sensor that utilizes a reflex mirror to split or direct light into the viewfinder to produce an image. [62] The reflex mirror finds the image by blocking light to the camera's sensor and then reflecting it into the camera's pentaprism which allows it to be seen through the ...
