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
