Patent number: 7889445Abstract: A lens actuation device for an optical system includes a housing, a carrier at least partially installed in the housing, and a plurality of transducers arranged around the carrier in the housing. All the transducers are coupled with the mount, and at least one transducer includes at least one magnet and at least one coil. At least one transducer includes at least one yoke. All the transducers when powered on may generate independent or consistent movement to cause the mount to make linear movement, rotation, or both relative to the housing. An optical system adopting the lens actuation device and a camera using the same are also presented. The device of the present invention uses the transducers to drive the carrier, such that the lens set is driven to make linear movement, rotation, or both, thereby achieving the flexible manipulation of the lens.Type: GrantFiled: October 30, 2008Date of Patent: February 15, 2011Assignee: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventors: Hua Yang, Sio Kuan Lam, Kwok Sing Cheng, Kin Ming Fan, Wing Ming Fan

Publication number: 20090244298Abstract: The invention discloses a imaging device, comprising an imaging module, used for optical to electrical signal conversion, which comprises at least a first imaging unit and a second imaging unit, the first imaging unit used for capturing an image, the second imaging unit used for detecting the movement of the image or the imaging device; a control and processing module, used for controlling the imaging module to output electrical signals, and for processing the electrical signal to generate and to output the motion signal and image signal. The invention also discloses an image capture device which uses the said imaging device. The imaging device can output the motion signal and the image signal simultaneously by adding the second imaging unit used for detecting the movement of the image or the imaging device; consequently better captured image quality can be obtained. Also, the structure can become simpler and the manufacture cost can be lower.Type: ApplicationFiled: March 24, 2009Publication date: October 1, 2009Applicant: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventors: Tiegang Liu, Sio Kuan Lam, Wing Ming Fan, Kin Ming Fan, Kwok Sing Cheng

Publication number: 20090237517Abstract: An optical module, a camera, and a mobile terminal device are provided. The optical module includes a lens unit, a lens driving unit, a driving control unit, and a vibration sensing unit. The vibration sensing unit is configured to detect vibration/shaking of the optical module, the camera, or the mobile terminal device and transmit a detected signal to the driving control unit. The driving control unit generates a corresponding vibration/shaking compensation signal according to the detected signal of the vibration sensor, and performs a vibration/shaking compensation movement by driving the lens with the lens driving unit. The optical module is applied in the camera and the mobile terminal device. The present invention has not only an auto-focusing function, but also an added anti-vibration function, so as to overcome influences on image degradation resulted from vibration/shaking of the optical module, the camera, or the mobile terminal device.Type: ApplicationFiled: March 24, 2009Publication date: September 24, 2009Applicant: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventors: Sio Kuan Lam, Kin Ming Fan, Tiegang Liu, Wing Ming Fan
