Abstract
A depth calculation method of a depth sensor includes outputting a modulated light to a target object, detecting four pixel signals from a depth pixel based on a reflected light reflected by the target object, determining whether each of the four pixel signals is saturated based on results of comparing a magnitude of each of the four pixel signals with a threshold value, and calculating depth to the target object based on the determination result.
