Digital photography was born with the development of the CCD (Charged Coupled Device), an array of light sensitive diodes. Engineers at Bell laboratories, in the late 1960’s, were working on capturing images digitally for use in computer memories, primarily for use in video telephony.
Today, CCD and CMOS (Complementary Metal Oxide Semiconductors) arrays are primarily used in still and motion (video) cameras.
