Digital camera information about the astronauts' position. As with Texas Instruments employee Willis Adcock's filmless camera (US patent 4,057,830) in 1972, the technology had yet to catch up with the concept. The Cromemco Cyclops was an all-digital camera introduced as a commercial product in 1975. Its design was published as a hobbyist construction project in the February 1975 issue of "Popular Electronics" magazine, and it used a 32×32 Metal Oxide Semiconductor sensor. Steven Sasson, an engineer at Eastman Kodak, invented and built the first self-contained electronic camera that used a charge-coupled device image sensor in 1975. Early uses were mainly military and

In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which used a Fairchild 100×100 pixel CCD. On August 25, 1981 Sony unveiled a prototype of the Sony Mavica. This camera was an analog electronic camera that featured interchangeable lenses and a SLR viewfinder. In 1986, the Kodak Microelectronics Technology Division developed a 1.3 MP CCD image sensor, the first with more than 1 million pixels. In 1987, this sensor was integrated with a Canon
