<p>The present invention increases the recognition accuracy of an input image and rapidly obtains recognition results of a recognition subject. The present invention is characterized by containing: a ranking unit (112) that extracts a plurality of local feature quantities from an input image, references a registered image database (102) in which local feature quantities extracted from each of a plurality of recognition subject images that can be recognized are associated with each of a plurality of recognition subjects, and are registered, associates the plurality of local feature quantities extracted from the input image with the closest local feature quantities among the registered local feature quantities, and ranks the plurality of recognition subjects in accordance with the number of associated local feature quantities; a rotation processing unit (113) that, on the basis of each extracted local feature quantity, determines conversion information for converting the recognition subject images; and a verification processing unit (114) that performs a conversion using the determined conversion information and determines whether or not the recognition subject image and the input image are the same.</p> |
