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: In a case where a first coil enters an energized state, the first coil, a second coil, a detection magnet, and a Z-axis position sensor move in an X axis direction. In a case where the second coil enters an energized state, the second coil and the detection magnet move in a Z axis direction, but the first coil and the Z-axis position sensor do not move in the Z axis direction. The Z-axis position sensor is disposed so as to be spaced from the second coil, and the detection magnet is disposed on a side opposite to a second driving magnet with respect to the Z-axis position sensor. The Z-axis position sensor detects a displacement amount V of the detection magnet in the Z axis direction.

Abstract: An operation dial is disposed so as to swing between two barrels. The operation dial has a plurality of finger gripping portions that protrudes so as to be inclined with respect to the two barrels. The operation dial is urged by a torsion coil spring to a state in which the two finger gripping portions have the same tilt angle with respect to the two barrels. A reception member is pushed by rotation of the operation dial in one direction and rotation of the operation dial in the other direction due to a swing operation for the finger gripping portions. A switch main body is opened or closed by the pushing of the reception member.
