First thermographic camera In 1929, Hungarian physicist KÃ¡lmÃ¡n Tihanyi invented the infrared-sensitive (night vision) electronic television camera for anti-aircraft defense in Britain. The first thermographic cameras developed were infrared line scanners.
The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak. It used the then-new solid-state CCD (charge-coupled device, a high-speed semiconductor) image sensor chips developed by Fairchild Semiconductor in 1973.
