Claim 15:
16. A method of operating a depth map sensor, the method comprising:
generating a plurality of phase-shifted clock signals;
propagating the phase-shifted clock signals via first output lines to a first array of first pixels and via second output lines to a second array of second pixels, each first pixel comprising a first photodetector associated with a first pixel circuit comprising a first plurality of bins for accumulating events, each second pixel comprising a second photodetector associated with a second pixel circuit comprising a second plurality of bins for accumulating events, the phase-shifted clock signals being propagated to the first array of first pixels during a first period determined by a first enable signal and to the second array of second pixels during a second period having a duration different from a duration of the first period; and
selecting which of the first output lines and the second output lines each of the plurality of phase-shifted clock signals is applied.
