Granted it's a few years away from production but the potential is enormous.

"Existing CMOS sensors can record light 1,000 times brighter than their dimmest detectable light, a dynamic range of 1:1,000, while the Rochester technology already demonstrates a dynamic range of 1:100,000."

Ignjatovic and Bocko of the Department of Electrical and Computer Engineering, came up with a way to make the physical layout of the light-sensitive diodes simplify the computation. The normal way to perform compression includes a computation called the discrete cosine transform, which checks how much a segment of an image resembles a series of cosine waves. Both the image and the cosine waves are sampled at regular intervals and the transform requires that the image and cosine wave samples be multiplied together and added. Since the cosine wave samples can have a value anywhere between -1and +1, the computation requires multiplication by non-integers, which demands the bulk of the computing power.
chim siah...but very interesting...
