Patent number: 8340431Abstract: 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.Type: GrantFiled: November 14, 2008Date of Patent: December 25, 2012Assignee: Altek CorporationInventors: Tzu-Chih Lin, Huan-Chun Lo

Patent number: 7978987Abstract: In an image forming apparatus, an image forming portion forms an image on a rotator. A storage portion stores change characteristics information relevant to correction parameters corresponding to phase points of the rotator. A designating portion sequentially designates the correction parameters based on the change characteristics information. A correcting portion corrects an image forming position on the rotator based on the correction parameter designated by the designating portion. When it is determined, based on a detecting phase point of the rotator detected by a detecting portion, that the current phase of the rotator corresponds to a gradual phase point at which the correction parameter changes at a rate equal to or lower than a predetermined value, the designation by said designating portion is shifted to the correction parameter corresponding to the gradual phase point.Type: GrantFiled: September 17, 2008Date of Patent: July 12, 2011Assignee: Brother Kogyo Kabushiki KaishaInventor: Naoki Abe
