Abstract
An automatic photographing method with face recognition is applied in a camera having a detecting lens and a photographing lens for a user to photograph a target. First, detect a face of the user through the detecting lens, and obtain a plurality of face images of the detected face. Then, capture an image variance of the obtained face images, and photograph the target through a photographing lens when the captured image variance exceeds a photographing starting value. Therefore, during the whole photographing process, photographing can be achieved through determining variations of the face images of the user without pressing the shutter key of the camera, thereby completely preventing handshakes resulted from the pressing action, and thus improving the photographing quality.
