The invention relates to an electronic device for analyzing a scene, including a plurality of pixels (101) connected to a readout circuit (103) by a same first conductive track (105), wherein: each pixel (101) is capable of detecting an occurrence of a first event characteristic of the scene and of transmitting an event indication signal on the first conductive track (105) when it detects an occurrence of the first event; and the readout circuit (103) is capable of reading from the first conductive track (105) the event indication signals transmitted by the pixels (101) and of deducing therefrom characteristics of the scene, without transmitting event acknowledgement signals to the pixels (101).
