2. Steven J. Sasson was born July 4, 1950 in Brooklyn, New York
USA, he was an American electrical engineer
Steven Sasson was who invented the digital camera in 1975 at
the age of 24
In 1989 he led the development of the first prototype mega pixel
electronic digital camera utilizing DCT compression that stored
images to flash memory cards. Steven continued his work
throughout the 1990’s by developing one of the first photographic
quality thermal printing systems, derivatives of which are still in
use in self-service imaging kiosks around the world today.
WHO INVENTED THE FIRST DIGITAL CAMERA?

3. HISTORY OF DIGITAL CAMERA
In 1969, E. Smith and Willard Sterling Boyle developed the
plans for the CCD sensor. Six years later, Steven Sasson, who
was later awarded the National Medal of Technology and
Innovation
In 1994, before Apple revolutionized the cell phone
market and while Steve Jobs was still fired, they
released the first successful digital camera on the
consumer market, the Quicktake 100.
In 1997, a decade before the iPhone, Philippe Kahn
took and shared the world’s first cell phone image.

4. USE OF DIGITAL CAMERA
The digital camera, records and stores
photographic images in digital form. Many current
models are also able to capture sound or video, in
addition to still images. Capture is usually
accomplished by use of a photosensor, using a
charged coupled device (CCD).These stored
images can be uploaded to a computer
immediately or stored in the camera for to be
uploaded into a computer or printer later. Images
may also be archived on a photographic compact
disc or external hard disk.

5. CONCLUSIONS
• This technology has revolutionized the world of photography, things
are very different from the old cameras. The digital cameras have
more advantages, such as: view the picture on an LCD screen,
buttons of copy, paste, zoom and delete. The photos are saved in
digital format this allows us to save them on computers where can be
edited and shared.
