摘要

In accordance with an aspect of the invention, high-accuracy matching result is obtained even if a condition in which an input image is photographed differs from a condition in which a registration image is photographed. In a face matching device (10), the registration face image and a photographing condition in which a person included in the registration face image is photographed are registered in a registration face image database (21) while the registration face image and the photographing condition correspond to each other. The face matching device (10) incudes a condition detecting unit (32), a registration face image selecting unit (35), and a matching unit (36). The condition detecting unit (32) detects a photographing condition in which the person included in the input face image is photographed. The registration face image selecting unit (35) determines closeness of the photographing condition of the registration face image and the photographing condition detected from the input face image, and selects the photographing condition closest to the photographing condition detected from the input face image in the photographing conditions of the registration face images registered common to the persons based on the determined closeness of the photographing condition. The matching unit (36) performs matching using the registration face image corresponding to the selected photographing condition.
