Digital photography uses an array of electronic
photodetectors to capture the image focused by
the lens, as opposed to an exposure on photographic
film. The captured image is then digitized and
stored as a computer file ready for digital processing,
viewing, digital publishing or printing.
Until the advent of such technology, photographs
were made by exposing light sensitive photographic film,
and used chemical photographic processing to develop
and stabilize the image. By contrast, digital photographs
can be displayed, printed, stored, manipulated,
transmitted, and archived using digital and computer t
echniques, without chemical processing.
Digital photography is one of several forms of
digital imaging. Digital images are also created by
non-photographic equipment such as computer
tomography scanners and radio telescopes.
Digital images can also be made by scanning other
photographic images.
The first recorded attempt at building a digital
camera was in 1975 by Steven Sasson, an engineer
at Eastman Kodak. It used the then-new solid-state
CCD image sensor chips developed by Fairchild
Semiconductor
in 1973.
The camera weighed 8 pounds (3.6 kg), recorded black
and white images to a cassette tape, had a resolution
of 0.01 megapixels (10,000 pixels), and took 23 seconds
to capture its first image in December 1975.
The prototype camera was a technical exercise,
not intended for production.
The first true digital camera that recorded images as a computerized file
was likely the Fuji DS-1P of 1988, which recorded to a 16 MB internal
memory card that used a battery to keep the data in memory. This camera
was never marketed internationally, and has not been confirmed to have
shipped even in Japan.
The first commercially available digital camera was the 1990 Dycam Model 1;
it also sold as the Logitech Fotoman. It used a CCD image sensor,
stored pictures digitally, and connected directly to a computer for
downloading images.
The first flyby spacecraft image of Mars was taken from Mariner 4 on July 15,
1965 with a camera system designed by NASA/JPL. It used a video camera
tube followed by a digitizer, rather than a mosaic of solid state sensor elements,
so it was not what we usually define as a digital camera, but it produced a
digital image that was stored on tape for later slow transmission back to earth.
