Depth map sensor with bin rotation

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.

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.
