Abstract
A camera shake correction apparatus includes a target position setting unit, a current setting unit, a driving unit, a magnetic flux detector, and an arithmetic unit. The target position setting unit sets a target position of a movable member. The current setting unit sets a current value to move the movable member to the target position. The driving unit drives the movable member with respect to a fixed member based on the set current set value. The magnetic flux detector detects a magnetic flux value changed with movement of the movable member. The arithmetic unit calculates a third magnetic flux value by subtracting a second magnetic flux value estimated to be generated from the driving unit based on the current set value from a first magnetic flux value actually detected by the magnetic flux detector.
