A face comparison device according to the present invention includes: an occluded-feature point estimation unit that estimates an occluded-feature point that is a feature point of an invisible face, and outputs position information of the occluded-feature point; a pseudo-feature point estimation unit that estimates a pseudo-feature point that is an erroneously detected feature point not captured within the input image due to occlusion, and outputs position information of the pseudo-feature point; and a comparison unit that generates a normalized image of the input image by using the position information of the occluded-feature point and the pseudo-feature point, generates a normalized image of an acquired comparison image, and compares the first facial feature vector extracted from the normalized image of the input image and the second facial feature vector extracted from the generated normalized image of the comparison image.
