Abstract
A time-of-flight ranging system includes an array of single photon avalanche diode (SPAD) pixels, and control circuitry that causes the array of SPAD pixels to integrate SPAD event data received from each SPAD pixel of a first cluster of SPAD pixels during a first illumination of a target, the first cluster of SPAD pixels being a subset of the array of SPAD pixels, and integrate SPAD event data received from each SPAD pixel of a second cluster of SPAD pixels during a second illumination of the target, the second cluster of SPAD pixels being a subset of the array of SPAD pixels. At a start of integration of the SPAD event data received from each SPAD pixel of the second cluster of SPAD pixels, the integrated SPAD event data that was received from each SPAD of the first cluster of SPAD pixels is accumulated.
