Revolutionary new chip delivers better pictures

Two professors at the University of Rochester in New York have designed a prototype CMOS chip that uses a fraction of the energy used today, captures better images and can run for years on a single battery. Mark Bocko, professor of electrical and computer engineering and assistant professor Zeljko Ignjatovic, are also working to incorporate further technology that will compress the image with far fewer computations than current compression techniques. It's likely that the technology will be tested first in wireless security cameras, and, Bocko says, as the chips are developed further, they will look into using them in consumer cameras and cell phones.

Breakthrough chip delivers better digital pictures for less power
Tiny cameras could run for years

The next advance in cameras is becoming a reality at the University of Rochester. Imaging chips revolutionized the photography industry, and now the chips themselves are being revolutionized. A pair of newly patented technologies may soon enable power-hungry imaging chips to use just a fraction of the energy used today and capture better images to boot - all the while enabling cameras to shrink to the size of a shirt button and run for years on a single battery. Placed in a home, they could wirelessly provide images to a security company when an alarm is tripped, or even allow mapping software like Google's to zoom in to real-time images at street level. The enormous reduction in power consumption and increase in computing power can also bring cell-phone video calls closer to fruition.

The team of Mark Bocko, professor of electrical and computer engineering, and Zeljko Ignjatovic, assistant professor of electrical and computer engineering, has designed a prototype chip that can digitize an image right at each pixel, and they are working now to incorporate a second technology that will compress the image with far fewer computations than the best current compression techniques.
