Abstract: The present disclosure relates to a depth map sensor including a light source for transmitting light pulses into an image scene; an array of pixel circuits, where each pixel circuit has a photodetector and three asynchronous counters; and a control circuit to control each of a plurality of groups of the pixel circuits of the array to generate a histogram of detection events by accumulating events during eight distinct time intervals between consecutive light pulses transmitted by the light source, such that the histogram comprises eight or more histogram bins.
