Abstract
Apparatuses, methods and programs store a plurality of target types, each target type having recognition attribute information indicating the likelihood that the target type will be recognized based on a type of road or a type of area. The apparatuses, methods and programs acquire vehicle position information indicating a current position of a vehicle, acquire image information in the vicinity of the vehicle, and acquire road attribute information about a road on which the vehicle is traveling, the road attribute information acquired based on the vehicle position information. The apparatuses, methods and programs determine a target type defining a target for image recognition within the image information, the target type being determined based on the acquired road attribute information and the stored recognition attribute information, and perform image recognition of a target feature included in the image information, the target feature being of the determined target type.
