1. A method for determining distance information based on Time of Flight (ToF) sensor data, the method comprising:
obtaining the ToF sensor data, wherein the ToF sensor data is based on a sensing of light incident to a ToF sensor;
determining one or more saturated regions within the ToF sensor data;
identifying one or more boundary regions located adjacent to the one or more saturated regions within the ToF sensor data, based on an intensity of the sensed light of the one or more boundary regions within the ToF sensor data;
determining an extent of the one or more boundary regions based on an intensity differential between the one or more boundary regions and adjacent regions within the ToF sensor data;
determining distance information for the one or more boundary regions based on the ToF sensor data and taking into account the extent of the one or more boundary regions; and
determining distance information for at least a part of the one or more saturated regions based on the distance information of the one or more boundary regions.
