Tips for Best Face Recognition Results • Face recognition in the Family First mode is slightly faster than that in the Normal mode. Also, compared with the Normal mode, the Family First mode will not be able to detect faces that are far away and small. • The camera performs center focus if it cannot detect a face.• Always make sure that Auto Focus (AF) is selected as the focus mode when shooting with face recognition. • Face recognition may take a bit longer when you hold the camera sideways.• Even if you have the face of a family member pre-recorded, the person’s facial expression, shooting conditions, or other factors can make proper detection (highest priority assignment) impossible. • Face recognition can be improved by pre-recording multiple versions of the same person’s face indoors and outdoors, with different expressions, and at different angles. • Detection of the following types of faces is not supported. – Face that is obstructed by hair, sunglasses, a hat, etc., or a face in dark shade– A profile or a face that is at an angle– A face that is very far away and small, or very close and large– A face in an area that is very dark– The face of a pet or some other non-human subject
