Claim One:
1. A face identification apparatus comprising: a face identification measure for identifying a face of an object person, based on an image of said object person taken by a camera; a face region expectation measure for expecting a face region of said object person in said image, based on distance information representing a distance from said camera to said object person, and profile information and flesh-color region information of said object person generated from said image; a pupil-candidate-point detection measure for generating a standard image with converting said face region to an image of a standard size, based on said distance information, setting a search region with making it a standard a center of gravity of said face region in the standard image, searching a circular edge for each pixel included in the search region, and detecting a right pupil candidate point and left pupil candidate point of said object person out of pixels of a predetermined circular edge; a reference data generation measure for rotating said standard image so that a line segment connecting said right pupil candidate point and said left pupil candidate point becomes horizontal within said standard image, then generating a normalization image with making it a standard a distance of said right pupil candidate point and said left pupil candidate point, and making reference data for evaluating advisability of said face region from the normalization image; and a face region evaluation measure for obtaining a degree of approximation between said reference data and standard data prepared in advance and evaluating the advisability of said face region, based on the obtained degree of approximation.
