Abstract: A first image blur correction device includes an imaging-element holding-member to which an imaging-element is fixed, a housing that supports the imaging-element holding-member to be movable in a direction X perpendicular to an optical axis of a lens device, and a first drive mechanism that generates thrust of moving the imaging-element holding-member in the direction X. The first drive mechanism includes a first magnet that is fixed to the housing and in which a direction connecting both magnetic poles is parallel to the direction X, and a first coil that is fixed to the imaging-element holding-member to face the first magnet. In a state where the imaging-element holding-member is at a reference position where the optical axis of the lens device coincides with a center of the imaging-element, a position of a first magnet center in the direction X and a first coil central axis deviate from each other.

Abstract: The image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit. The system control unit selects one of rotation axes based on a usage state of a digital camera, and calculates a shift blur amount generated in a direction by rotation of the digital camera around a second axis and a shift blur amount generated in a direction by rotation of the digital camera around a first axis based on distances from the selected rotation axis to the acceleration sensor, angular velocities, and accelerations.

Abstract: An image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit that calculates rotational acceleration components which are included in detected accelerations and are generated by rotation of a digital camera around a rotation axis parallel to an optical axis, and corrects blurs of the captured image signal in directions based on accelerations obtained by subtracting the rotational acceleration components from the accelerations detected by the acceleration sensor. The system control unit selects one of rotation axes based on a usage state of the digital camera, and calculates the rotational acceleration components generated by the rotation of the digital camera around the selected rotation axis based on an angular velocity and distances in the directions from the selected rotation axis to the acceleration sensor.

Abstract: Barrels are attached so as to be rotated around first rotational axes. Reflective members are fixed to the barrels, and reflective members are attached so as to be rotated around second rotational axes. Rotation amounts are equal to each other in rotation of the pair of left and right barrels around the first rotational axes and rotation of the reflective members of the barrels around the second rotational axes due to a link mechanism having a first link member and a second link member. Image blurring in a yaw direction is corrected due to movement of the first link member in an X axis direction. Image blurring in a pitch direction is corrected due to movement of the second link member in a Y axis direction.
