<p>PROBLEM TO BE SOLVED: To improve collation accuracy in a system which determines whether a face included in a captured image is coincident with a registered face, on the basis of a similarity between the face included in the captured image and a face included in a registered image registered in advance.SOLUTION: An image registration device includes a partial face reliability acquisition section which acquires a partial face reliability indicating likelihood of a part of a face included in a registered image when a face reliability of an input image is lower than a first reference face reliability determined based on a face reliability of the registered image, and a partial face reliability indicating likelihood of a part of a face included in the input image. A registered image update section registers the input image, as a new registered image, in place of the former registered image, in the registered image storage section, when the partial face reliability of the input image is equal to or higher than a reference partial face reliability determined based on the partial face reliability of the registered image.</p> |
