Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An imaging system comprising:
a semiconductor device comprising a plurality of single-photon avalanche diodes; and
control circuitry configured to:
set a bias voltage for the plurality of single-photon avalanche diodes to a first voltage level during a first sub-exposure;
expose the plurality of single-photon avalanche diodes to light pulses during the first sub-exposure;
set the bias voltage for the plurality of single-photon avalanche diodes to a second voltage level during a second sub-exposure, wherein the second voltage level is different than the first voltage level; and
expose the plurality of single-photon avalanche diodes to additional light pulses during the second sub-exposure; and

image processing circuitry configured to generate a depth map based on data from the first and second sub-exposures.
