To provide a de-noising device, a de-noising method and a computer readable medium capable of reducing the influence of noise included in waterfall data. A de-noising device comprises: a determination unit (241) for determining end coordinates of each of a plurality of trajectories extracted from waterfall data, the waterfall data being acquired by measuring signals from a plurality of sensing portions arranged along a road; an extension unit (242) for extending each trajectory by using the end coordinates so that a duration of time of each 10 trajectory becomes a reference duration of time; a feature calculation unit (243) for calculating a feature of each extended trajectory; a detection unit (244) for detecting an outlier trajectory from the plurality of trajectories based on the features; a removing unit (245) for removing the outlier trajectory from the plurality of trajectories.
