Few Facts Of Digital Cameras
A digital camera captures images in a digital format, unlike a conventional camera, which captures images using a photographic film.
History:
Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be produced in a digital domain. An engineer at Eastman Kodak, Steve Sasson, used solid - state CCD chips to build a prototype digital camera having a resolution of 0. 01 megapixel, and recorded black and white digital images to a magnetic cassette tape. With this prototype model, Steve took the first image in December of 1975 taking 23 seconds to capture it.
In 1988, Fuji DS - 1P became the first digital camera that captured images as a computerized file. However, the camera never entered the U. S. market. In 1991, Kodak DCS - 100 was the first commercially available digital camera, which used a 1. 3 megapixel sensor. With the advancement of technology, modern digital cameras have become multifunctional and are now capable of capturing audio / video and still photographs. Read More..
