Abstract
A digital camera includes a vibration detector, an imaging element shift mechanism that corrects a shake of an image captured by an imaging element, and a system control unit, in which the system control unit performs a first control of driving the imaging element shift mechanism based on vibration information output from the vibration detector, and in a case where it is determined to be in a first state based on the vibration information, predicts the vibration information (angular velocity) output from the vibration detector at a timing of finish of the first state.

A shake correction device comprising:
- a vibration detector;
- a shake correction mechanism that corrects a shake of an image captured by an imaging element;
- and
- a processor,
- wherein the processor is configured to
- perform a first control of driving the shake correction mechanism based on vibration information output from the vibration detector, and
- in a case where it is determined to be in a first state based on the vibration information, predict the vibration information to be output from the vibration detector at a timing of finish of the first state,
- wherein the processor is configured to, in a case where it is determined to be in the first state after a start of the first control, hold a position of a movable unit of the shake correction mechanism at a holding position based on the predicted vibration information at at least the timing of the finish of the first state, and
- wherein the processor is configured to determine the holding position based on a first position and a first movement distance, the first movement distance being a movement distance of the movable unit in a case where the first control is performed based on the predicted vibration information.
A shake correction method comprising:
- performing a first control of driving a shake correction mechanism that corrects a shake of an image captured by an imaging element based on vibration information output from a vibration detector;
