  • Blur correction device, interchangeable lens and image-capturing device
    Patent number: 11696028
    Abstract: A blur correction device includes a blur correction element that is movable to correct blurring of a subject image formed via an image-capturing optical system, a motion sensor that detects a motion of a device equipped with the blur correction device, an input unit to which information indicating a position on an image sensor that captures the subject image is input, and a drive unit that moves the blur correction element based on the position and the motion. In a case where the position is different, the direction of the blur correction element moved based on the motion is different.
    Type: Grant
    Filed: October 15, 2021
    Date of Patent: July 4, 2023
    Assignee: NIKON CORPORATION
    Inventors: Daiju Nakajima, Tsuyoshi Matsumoto, Yoshiko Ono, Eiji Mikamoto

  • Blur correction device, interchangeable lens and image-capturing device
    Patent number: 11178328
    Abstract: A blur correction device includes: an input unit to which a blur quantity in at least either an image-capturing optical system or an image sensor that captures a subject image formed via the image-capturing optical system, is input; and a calculation unit that calculates, based upon the blur quantity, a correction quantity for correcting blur in the subject image, wherein: the calculation unit calculates a second correction quantity different from a first correction quantity for correcting blur in the subject image occurring on an optical axis.
