  • Publication number: 20200396386
    Abstract: A method of correcting an optical axis of a zoom lens includes obtaining a degree of optical axis misalignment corresponding to a current zoom lens state of a camera, considering the current zoom lens state of the camera and data previously stored to define a relationship between a state of the zoom lens of the camera and the degree of optical axis misalignment, determining digital zoom information to compensate for the degree of optical axis misalignment, considering the degree of optical axis misalignment, and generating correction image data by cropping and magnifying image data photographed by the camera to correspond to the digital zoom information.

  • Patent number: 10855247
    Abstract: An elliptical-shaped resonator device. The device includes a bottom metal plate, a piezoelectric layer overlying the bottom metal plate, and a top metal plate overlying the piezoelectric layer. The top metal plate, the piezoelectric layer, and the bottom metal plate are characterized by an elliptical shape having a horizontal diameter (dx) and a vertical diameter (dy), which can be represented as ellipse ratio R=dx/dy. Using the elliptical structure, the resulting bulk acoustic wave resonator (BAWR) can exhibit equivalent or improved insertion loss, higher coupling coefficient, and higher quality factor compared to conventional polygon-shaped resonators.
