  • Patent number: 8264551
    Abstract: A method and an apparatus for correcting distortions of image-taking video signals are provided. The method and an apparatus adopting the method are capable of reducing distortion generated in a taken image by correction of inter-frame and intra-frame hand movements in an image-taking apparatus employing an image-taking device of an X-Y address type. To be more specific, this method is capable of correcting distortion observed in a taken image as distortion caused by a positional change, which occurs in the horizontal and/or vertical directions of the taken image at a photographing time as a positional change of the image-taking device. In accordance with the method, in a frame period of a taken image, an inter-frame correction quantity for a positional change of the device is detected and, on the basis of the detected inter-frame correction quantity, the positional change is corrected to eliminate a displacement observed when the frame changes to the next one as a displacement of the taken image.

  • Patent number: 8259211
    Abstract: A lens driver includes a lens unit, a polymer actuator, and an orthogonal transformation mechanism. The lens unit includes a lens holding frame having a pressed portion at an outer peripheral surface of the lens unit, a lens being held thereby. The lens unit is movable in an optical-axis direction of the lens. The polymer actuator is arranged outside the outer peripheral surface and having an electrode to which a voltage is applied. The polymer actuator is bent in a direction orthogonal to the optical-axis direction and presses the pressed portion in that direction when the voltage is applied to the electrode. The orthogonal transformation mechanism converts a force in a pressing direction into a moving force in the optical-axis direction and moves the lens unit in the optical-axis direction when the pressed portion of the lens holding frame is pressed by the bent polymer actuator.
