Steve Sasson created the world’s first digital camera in 1976, while working at Kodak. He discusses the development of the camera in this video.
It was a camera that didnâ€™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.
Given Moore’s Law, they estimated that it would take 15 to 20 years before such a camera reached the general consumer. The patent file contains a description and drawings of the apparatus.
