  • Patent number: 10924672
    Abstract: An operation part calculates a shake amount of an imaging apparatus in accordance with a first operation system or a second operation system on the basis of an output signal of a sensor detecting an acceleration or angular velocity to determine a camera-shake correction amount correcting the shake amount. The operation part calculates the output signal of the sensor or a value obtained by integrating an integrated signal of the output signal of the sensor as a shake amount. The operation part includes an imperfect integrator. An operation system setting part sets an operation system of the operation part on the basis of the shake amount calculated by the operation part. In the second operation system, the operation system setting part increases a cut-off frequency of the imperfect integrator more than in the first operation system.

  • Publication number: 20180184005
    Abstract: In open-loop control, displacement of a correction lens cannot be detected. Therefore, the displacement of the correction lens cannot be appropriately corrected. To solve this problem, in a camera controller, a first storage unit stores therein a first correction amount for a standard tilt of a camera module with respect to a first force in which its acting direction in a camera coordinate system varies in accordance with a tilt of the camera module. A controller calculates an image stabilization amount, obtains a tilt correction amount for a tilt of the camera module based on the tilt of the camera module and the first correction amount, and controls a position of a correction lens included in an optical system in such a manner the correction lens is shifted within a plane perpendicular to an optical axis based on the image stabilization amount and the tilt correction amount.
