1. A vision system responsive to a visual environment comprising:
- a plurality of photoreceptor circuits configured to generate a plurality of raw photoreceptor signals from the visual environment;
a plurality of pooling mechanisms configured to generate a plurality of pool signals based on the plurality of raw photoreceptor signals, wherein each pooling mechanism of the plurality of pooling mechanisms is selected from the group consisting of a spatial pooling mechanism, a temporal pooling mechanism, and a spatial-temporal pooling mechanism; and
an image processing mechanism configured to generate an output based on the plurality of pool signals.

Abstract
A vision system for use in dark environments is disclosed. The vision system comprises photoreceptor circuits for generating photoreceptor signals, pooling mechanisms for generating pool signals, and an image processing means. The structure of the vision system is inspired from that of nocturnal flying insects. Applications are disclosed including use of the vision system on a mobile platform such as an air vehicle to enable perception and flight stability in dark environments.
