History of digital cameras
exactly digital cameras were invented is a matter of debate. Like chemical
based photography the precise point at which digital photography was invented
is open to interpretation. Was it the drum scanner constructed by Russell
A Kirsch and his colleagues at the National Bureau of standards in the
1950s that recorded visual information on a raster grid?

of the first digital images. The image was scanned forma photograph
by a BNS mechanical drum scanner then processed by a SEAC computer
and displayed on an oscilloscope.
Was it the digital imaging techniques that NASA used to correct imperfections,
that ran as trace lines caused by transmission static, from images of
the Luna surface sent back by Ranger 7 in 1964?
it in the late 1980s when Canon, Nikon and Sony introduced compact, high
quality, still-video cameras that recorded images directly on miniature
floppy disk and provided an alternative to the silver film processes?

of the technology continued until during the late 1990s, digital cameras
exploded into the consumer and professional market. Within as few as 3
years they grew from about 3-5% to 97% of the market. The consumer was
bombarded with a plethora of new terms and figures. Mega pixels, CCD.

development of the digital camera continues with seamless integration
into other electronic devices such as phones, computers etc. To attempt
to keep abreast with the current developments would be a full time occupation.
However, there are there are some things that remain constant. For instance
- many of the optical principles that apply to film cameras also hold
true for digital.
