Shake correction device

A shake correction device comprising:

• a fixed member on which one of three drive coils and three drive magnets are arranged;
• a movable member on which one of an optical element and an image sensor, and the other one of the three drive coils and the three drive magnets are arranged, the movable member being movable with respect to the fixed member, and the three drive magnets facing the three drive coils;
• three detection magnets arranged on the fixed member or the movable member on which the three drive magnets are arranged;
• three detectors arranged on the fixed member or the movable member on which the three drive coils are arranged, wherein the three detectors face the three detection magnets and detect a change in magnetic flux generated according to a change in distance to the three detection magnets;
• a movement amount calculator which calculates movement amounts and movement directions of operating points in the three drive coils based on outputs from the three detectors;
• and
• a drive controller which moves the movable member by controlling currents to apply to the three drive coils based on outputs from the movement amount calculator,
• wherein the three detectors and the three detection magnets form pairs, respectively, each pair being arranged between respective neighboring ones of the three drive coils, and
• wherein the movement amount calculator uses outputs from two or three of the three detectors to calculate the movement amounts and the movement directions of the operating points in the respective three drive coils.
