A method of using an optical TOF module to determine distance to an object. The method includes acquiring signals in the TOF module indicative of distance to the object, using a first algorithm to provide an output indicative of the distance to the object based on the acquired signals, using at least one second different algorithm to provide an output indicative of the distance to the object basedon the acquired signals, and combining the outputs of the first and at least one second algorithms to obtain an improved estimate of the distance to the object. In some implementations, each of the first and at least one second algorithms further provides an output representing a respective confidence level indicative of how accurately distance to the object has been extracted by the particular algorithm. 本发明揭示一种使用一光学TOF模组来判定至一物件之距离之方法。该方法包含：在该TOF模组中获取指示至该物件之距离的信号；使用一第一演算法以基于该等经获取信号来提供指示至该物件之该距离之一输出；使用至少一第二不同演算法以基于该等经获取信号来提供指示至该物件之该距离之一输出；及组合该第一演算法之该输出与该至少一第二演算法之该输出以获得至该物件之该距离之一改良估计。在一些实施方案中，该第一演算法及该至少一第二演算法之各者进一步提供表
