Abstract
The present disclosure describes a method and apparatus for enabling an imaging sensor to perform Time-of-Flight measurements while requiring less histogram memory and in many cases less power consumption. A light source is operated to cause multiple light emissions and a coarse/estimated distance is determined based on a first echo received based on the first light emission. A histogram is saved and a fine distance is calculated from the coarse distance and data derived from the echo of a second light emission.
