Claim One:
1. A face image processing apparatus selecting feature points and features used for identifying a person through statistical learning and performing a personal identification process using the selected feature points in a synthetic manner, the apparatus comprising: an input unit configured to input a face image detected by arbitrary face detection means; a face parts detection unit configured to detect positions of face parts in several locations from an input face image, including roughly estimating a face pose angle from a plurality of face detection results which are in an overlapping relationship; a face pose estimation unit configured to estimate face pose based on detected positions of face parts; a feature point position correcting unit configured to correct a position of each feature point used for identifying the person based on a result of estimation of face pose by the face pose estimation unit; and a face identifying unit configured to identify the person by calculating a feature of the input face image at each feature point after position correction is performed by the feature point position correcting unit and by checking the feature against a feature of a registered face.
