Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A camera shake correction apparatus driving a movable member including an optical member or an imaging member with respect to a fixed member, based on a detected camera shake amount, comprising: a target position setting unit setting a target position to which the movable member is to be moved based on the camera shake amount; a current setting unit setting a current value to move the movable member to the target position; a driving unit formed of a c…
