A photography unit (20) is mounted on a vehicle (2) so as to capture an image of an area including a road around the vehicle. A shadow detection unit (11), on the basis of differences based on a comparison, between a plurality of elements configuring the image, of the degree of a specific color component and brightness included in the color represented by each element, detects a shadow region from the image which is a region in which a shadow is on the surface of the road. A feature point detection unit (12) detects a feature point from the image. A shadow edge removal unit (13) removes, from a group of detected feature points, a feature point corresponding to an edge of the shadow region. A recognition unit (14) recognizes, from the feature point group after the edge of the shadow region has been removed, a specific object that exists around the vehicle.
