Face recognition method and apparatus

A face recognition apparatus, comprising:

• a sound receiving device, configured to detect a sound source;
• an image capturing device, configured to capture an image;
• a processor, coupled to the sound receiving device and the image capturing device, and configured to:
• detect a direction of a sound source by using the sound receiving device to capture an image in the direction by using the image capturing device;
• detect and track a face in the image to assign an image identification to the face according to a tracking result;
• determine whether the image identification exists in a plurality of cluster identifications already recognized in a data set of face recognition;
• and
• in response to the image identification not existing in the data set, acquire a feature value of the face, and compare the feature value of the face with a feature value of a face of each of the cluster identifications to update a cluster identification to which the face belongs according to a comparison result, wherein the image capturing device is a panoramic camera, and the processor is configured to:
• capture a panoramic image around the electronic device by using the image capturing device, and crop a partial image in the direction in the panoramic image as an image on which the face recognition is performed.
