Document Type and Number:
WIPO Patent Application WO/2017/147999
Kind Code:
A1
Abstract:
An electronic device, a face recognition and tracking method and a three-dimensional display method. The electronic device (100) comprises: a camera apparatus (110) configured to photograph a face image of a user; a front face image acquisition module (120) for acquiring a front face image of the user by means of the camera apparatus (110); a face tracking module (130) for performing a comparison operation on the face image photographed by the camera apparatus (110) and the front face image so as to determine a moving distance of the face of the user in a planar direction perpendicular to a central optical axis of the camera apparatus (110), wherein the comparison operation comprises comparing the ratio of the area of a specific portion in the face image photographed by the camera apparatus (110) to the area of the whole face with the ratio of the area of the specific portion in the front face image to the area of the whole face. The electronic device (100) can recognize and track the face of the user.
