Digital imaging was developed in the 1960s and 1970s, largely to avoid the operational weaknesses of film cameras, for scientific and military missions including the KH-11 program. As digital technology became cheaper in later decades, it replaced the old film methods for many purposes.
Photograph scanned into a digital computer, 1957. 1956 - The Chemigram was defined by the belgian artist Pierre Cordier. 1957 First Asahi Pentax SLR introduced. First digital computer acquisition of scanned photographs, by Russell Kirsch et al. at the U.S. National Bureau of Standards (now the NIST). [17] 1959 Nikon F introduced.
Rapid advances in digital imaging began with the introduction of MOS integrated circuits in the 1960s and microprocessors in the early 1970s, alongside progress in related computer memory storage, display technologies, and data compression algorithms.
It is a form of digital imaging based on gathering visible light (or for scientific instruments, light in various ranges of the electromagnetic spectrum). Until the advent of such technology, photographs were made by exposing light-sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize ...
By the late 1970s, the technology required to produce truly commercial digital cameras existed. The first true portable digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 2 MB SRAM (static RAM ) memory card that used a battery to keep the data in memory.
Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s, at Bell Laboratories, the Jet Propulsion Laboratory, Massachusetts Institute of Technology, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone ...

The 1970s witnessed an explosion in the understanding of solid-state physics, driven by the development of the integrated circuit and the laser. The evolution of the computer produced an interesting duality in the physical sciences at this period — analogue recording technology had reached its peak and was incredibly sophisticated.
