Abstract:
An image stabilization control apparatus having a compensation member comprises: first and second detection units that detect rotational and translational shakes, respectively, in the image stabilization control apparatus; a rotational shake amount calculation unit that finds a rotational shake amount based on an output of the first detection unit; a correction value calculation unit that calculates a correction value based on outputs from the first and second detection units; a suppression unit that suppresses the correction value based on the size of an output from the first and/or second detection units; a translational shake amount calculation unit that calculates a translational shake amount using the output of the first detection unit and the calculated correction value; and a driving unit that drives the compensation member based on the rotational and translational shake amounts, wherein the correction value is calculated based on the suppressed correction value.
