Abstract
A method of operating a time of flight system includes detecting first optical signals comprising a first frequency having a first unambiguous range, the first optical signals reflected from a target, processing the first optical signals to determine a first estimated distance to the target, and generating an output frame comprising a true distance to the target based on the first estimated distance and a second estimated distance to the target, wherein the second estimated distance was used to generate a previous output frame.
