4. • The first recorded attempt at building a digital camera was in 1975
by Steven Sasson, an engineer at Eastman Kodak.[1][2] It used the
then-new solid-state CCD image sensor chips developed by Fairchild
Semiconductor in 1973.[3] The camera weighed 8 pounds (3.6 kg),
recorded black and white images to a cassette tape, had a
resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds
to capture its first image in December 1975. The prototype camera
was a technical exercise, not intended for production.

• The first true digital camera that recorded images as a
computerized file was likely the Fuji DS-1P of 1988, which recorded
to a 16 MB internal memory card that used a battery to keep the
data in memory. This camera was never marketed in the United
States, and has not been confirmed to have shipped even in Japan.
