Abstract

An event-based vision sensor, comprises an array of event-based pixels, each pixel configured to record events based on variations of a sensed photocurrent and enable, at the occurrence of an event, a request line common to pixels aligned along an axis of the array; a request arbiter configured to respond asynchronously to the enabled request lines by enqueuing corresponding line readout requests in a request queue; an event readout circuit connected to the request arbiter and configured to readout in parallel the events of a line of pixels corresponding to a current line readout request served by the arbiter; a queue length counter connected to the request lines to produce the request queue length; a queue monitor connected to the queue length counter, configured to generate an event burstiness indicator; and means configured to carry out a burstiness compensation action based on the event burstiness indicator.
