Claim 9:
10. A method of operating a depth map sensor, the method comprising:
propagating, using a first sub-circuit of a first circuit comprising a plurality of first output lines coupled to a first array of first pixels, a plurality of phase-shifted clock signals received by the first circuit and generated by a clock source, to a second sub-circuit of the first circuit during a first period determined by a first enable signal, each first pixel comprising a first photodetector associated with a first pixel circuit comprising a first plurality of bins for accumulating events;
propagating, using a third sub-circuit of a second circuit comprising a plurality of second output lines coupled to a second array of second pixels, the plurality of phase-shifted clock signals received by the second circuit from the clock source, to a fourth sub-circuit during a second period with a duration different from a duration of the first period and determined by a second enable signal, each second pixel comprising a second photodetector associated with a second pixel circuit that comprises a second plurality of bins for accumulating events;
selecting, using the second sub-circuit, to which of the plurality of first output lines each of the plurality of phase-shifted clock signals is applied; and
selecting, using the fourth sub-circuit, to which of the plurality of second output lines each of the plurality of phase-shifted clock signals is applied.
