Zusammenfassung:	A method of time of flight sensing. The method comprises using an emitter to emit pulses of radiation and using an array of photo-detectors to detect radiation reflected from an object. For a given group of photo-detectors of the array, the method determines based upon measured times of flight of the radiation, whether to use a first mode of operation in which outputs from individual photo-detectors of the group are combined together or to use a second mode of operation in which outputs from individual photo-detectors are processed separately. The array of photo-detectors comprises a plurality of groups of photo-detectors. One or more groups of photo-detectors operate in the first mode whilst in parallel one or more groups of photo-detectors operate in the second mode.
