This is Kodak’s first digital camera made by the Kodak Apparatus Division Research Laboratory in 1975.

It was a camera that didn’t use any film to capture still images – a camera that would capture images using a CCD imager and digitize the captured scene and store the digital info on a standard cassette.  It took 23 seconds to record the digitized image to the cassette.  The image was viewed by removing the cassette from the camera and placing it in a custom playback device.  This playback device incorporated a cassette reader and a specially built frame store.  This custom frame store received the data from the tape, interpolated the 100 captured lines to 400 lines, and generated a standard NTSC video signal, which was then sent to a television set.
