How Neuromorphic Image Sensors Steal Tricks From the Human Eye

How Neuromorphic Image Sensors Steal Tricks From the Human Eye

We designed the level-crossing and recording circuits in our camera to react with blazing speed. With our equipment, data acquisition and readout times of a few tens of nanoseconds are possible in brightly lit scenes. For standard room-light levels, acquisition and readout require a few tens of microseconds. These rates are beyond all but the most sophisticated high-speed video cameras available today, cameras costing hundreds of thousands of dollars. And even if you could afford such a camera, it would deluge you with mostly worthless information. Sampling different pixels at different rates, on the other hand, reduces not just equipment cost but also power consumption, transmission bandwidth, and memory requirements—advantages that extend well beyond the acquisition stage. But you’ll squander those benefits if all you do is reconstruct a series of ordinary video frames f...
