Abstract
In one implementation, an event sensor includes a plurality of pixels and an event compiler. The plurality of pixels are positioned to receive light from a scene disposed within a field of view of the event sensor. Each pixel is configured to have an operational state that is modified by control signals generated by a respective state circuit. The event compiler is configured to output a stream of pixel events. Each respective pixel event corresponds to a breach of a comparator threshold related to an intensity of incident illumination. Each control signal is generated based on feedback information that is received from an image pipeline configured to consume image data derived from the stream of pixel events.
