Giga-pixel Camera Presented

Discovery News, Nature Journal: A group led by David Brady, EE professor at Duke's Pratt School of Engineering with scientists from the University of Arizona (UA), UCSD, and Distant Focus Corp. developed a Gigapixel camera named AWARE-2. The camera is said to use 98 microcameras, each with a 14MP sensor, grouped around a shared spherical lens. Together, they take in a field of view 120 degrees wide and 50 degrees tall. With all the packaging, data-processing electronics and cooling systems, the entire camera is about 0.75 by 0.75 by 0.5 metres in volume. 97% of the physical camera is comprised of the electronics and computer; only about 3% is devoted to the optical elements.
