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.
Claims14
A blur correction device, comprising:
- 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,
- wherein a movement direction of the blur correction element changes based on a change in the position.
A method for correcting blurring of a subject image by moving a blur correction element, the method comprising:
- detecting motion of a device;
- obtaining information indicating a position on an image sensor that captures a subject image;
- moving the blur correction element based on the position and the motion;
- and
- changing a movement direction of the blur correction element based on the position and the motion.
