Abstract
Methods for detecting a time-of-flight include: emitting a light pulse toward a target; detecting a presence of light received at a light detector; obtaining a delay time between emitting the light pulse and detecting the presence of the light at the light detector; responsive to obtaining the delay time, (a) updating an overall intensity counter that counts a total number of delay times that have been obtained and (b) updating a delay time counter out of a plurality of different delay time counters, wherein each delay time counter counts a total number of delay times obtained that have a corresponding delay time value; and monitoring a threshold of each delay time counter to determine whether a threshold value is exceeded.
