Abstract:
According to at least one example embodiment, a depth information error compensation method includes outputting modulated light to a target object, detecting a plurality of first pixel signals at different detection time points in a first time interval, the first pixel signals representing light reflected from the target object during the first time interval, detecting a plurality of second pixel signals at different detection time points in a second time interval, the second pixel signals representing light reflected from the target object during the second time interval, comparing each of the plurality of first pixel signals with each of the plurality of second pixel signals and calculating depth information to the target object according to the comparing.
