History of digital camera

In 1947, transistor was invented by three scientists in Bell Labs: John Bardeen, Walter Brattain and William Shockley.  Transistor later became the basic component of digital camera.

The digital camera was an outgrowth of the video tape recorder, first developed in 1951, and charge-couple device (CCD), invented in 1959 at Bell Labs.

Texas Instruments patented the first filmless digital camera for still images in 1972. The first digital camera was born in Kodak Company in 1975, but begun to produce civil product after 23 years in 1998.

In 1986 Kodak invented the first megapixel sensor which allowed the recording of 1.6 million pixels, allowing a 5 by 7 inch picture with quality equivalent to or better than a film picture.

The first consumer digital camera was launched in 1990 by the American company Dycam. In 1995, Casio Inc. and Canon Inc. respectively produced a digital camera.
