The first digital Image

In 1957, computer pioneer Russell Kirsch and his team unveiled a drum scanner for SEAC, to "trace variations of intensity over the surfaces of photographs", and so doing made the first digital image by scanning a photograph. The image, picturing Kirsch's three-month-old son, consisted of just 176×176 pixels. They used the computer to extract line drawings, count objects, recognize types of characters, and display digital images on an oscilloscope screen.
