Imaging Developer Claims Massive Low-Light Improvements

Author: Brian Karas, Published on Jul 27, 2016

In the early days of megapixel, binning was a crutch used to compensate for poor low-light performance.  Low-light sensitivity improvements have mostly eliminated the need for binning, but one company has an interesting argument for bringing it back.

We had a conversation with Rick Puetter, the Chief Scientist at Pixon Imaging about their "intelligent" binning approach, which they call ExDRA (Extended Dynamic Range Architecture).

This report examines Pixon's technology and its potential in the security market
