It is dif”cult to ”nd an exact starting point for the digital camera, so this chapter will start with the ”rst mention of it in a recognized publication. Eugene Lally was a NASA scientist who wrote a theoretical paper in 1961 that described digital photography using a mosaic array of photo detector circuits, analog to digital converters, and a place to send the resulting pictures [1]. Others will sometimes start the history of the digital camera with a story about Texas Instrument’s initiatives on a ”lmless camera in 1971.
