Zusammenfassung:In one implementation, an event sensor includes a plurality of pixels, an external readout line shared among the plurality of pixels, and an external processing circuit. Each pixel is configured to output pixel data indicative of an intensity of incident illumination. The external processing circuit is configured to output a stream of pixel events. Each respective pixel event is generated when a comparator of the external processing circuit obtains a sample of pixel data from a particular pixel via the external readout line that breaches a threshold value.
