Abstract: The method processes a series of events received asynchronously from an array of pixels of an event-based light sensor. Each event of the series comprises an address of a pixel of the array from which the event is received, and an attribute value depending on incident light sensed by that pixel. The method comprises: storing a data structure in a first memory, the data structure including event data for at least some of the pixels of the array, the event data for a pixel being related to at least one event most recently received from said pixel; during a timeslot, building, in a second memory having a faster access than the first memory, a map for the pixels of the array as the events of the series are received, the map including an information element for each pixel of the array, the information element having one of a plurality of values including a nil value indicating an absence of event during the timeslot; and updating the data structure after the timeslot using the map.
