Many people may not know this, but the world’s first digital camera was invented in 1975, by Kodak, and recorded images onto cassette tape. The camera had a 100 line black and white CCD sensor, and images could be played back (via a “Microcomputer”) and viewed on a TV screen. More information can be found on retrothing.com, and on the Kodak blog:
“In December of 1975, after a year of piecing together a bunch of new technology in a back lab at the Elmgrove Plant in Rochester, we were ready to try it. “It” being a rather odd-looking collection of digital circuits that we desperately tried to convince ourselves was a portable camera. It had a lens that we took from a used parts bin from the Super 8 movie camera production line downstairs from our little lab on the second floor in Bldg 4. On the side of our portable contraption, we shoehorned in a portable digital cassette instrumentation recorder.”
“Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on approximately half a dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like.” Images from Twitter/KodakCB.
