FACE AUTHENTICATION DEVICE AND FACE AUTHENTICATION METHOD

摘要

A face authentication device has a face image acquisition unit that continuously acquires face images of a user, a user identification unit that identifies the user based on a first face image acquired by the face image acquisition unit, a parameter acquisition unit that acquires a face parameter based on a second face image acquired by the face image acquisition unit, the face parameter being a parameter associated with a facial expression or a face direction of the user, a tracking unit that extracts a region of a part of a face included in the first face image, and to track the region between the plurality of continuously-acquired face images, and an authentication unit that makes a determination of successful authentication when the user identified by the user identification unit is a registered user, when the acquired face parameter satisfies a predetermined condition.
