A movement information estimation device estimates movement information on a mobile body based on information from a camera mounted on the mobile body. The movement information estimation device includes a feature point extractor configured to extract a feature point from a predetermined region in an image taken by the camera, and a movement information estimator configured to estimate movement information on the mobile body based on the feature point. If such a feature point as fulfills a particular condition is present, a particular extraction region is set instead of the predetermined region, and estimation of the movement information on the mobile body is performed based on the feature point extracted from the particular extraction region
