Abstract: A method for operating an event-based image sensor comprising a plurality of pixel circuits arranged to form a pixel array, each pixel being arranged at a location defined by an address defined by pixel coordinates in the array, wherein each pixel circuit is configured for generating an event, each time a light intensity change is detected, an event being characterized by a polarity reflecting a direction of the change, wherein the method comprises: - performing a line readout of groups of adjacent pixels of a line of pixels, the line readout comprises generating, for each group, at least one packet expressing occurrences of events of a same polarity in said group, a packet being characterized each packet is characterized by a polarity and a group address, - sending said packets to a processing pipeline where the packets are successively processed, involving a memory access based on the group address, wherein two packets sharing the same group address have different polarities and are consecutively processed.
