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. 本发明涉及一种操作飞行时间系统的方法，包括：探测包含具有第一无模糊范围的第一频率的第一光信号，该第一光信号是反射自目标；处理第一光信号以确定距目标的第一估计距离；以及基于第一估计距离和距目标的第二估计距离，生成包含距目标的真实距离的输出帧，其中，第二估计距离曾用于生成先前输出帧。
