US 8,509,610 B2 · Image stabilization control apparatus, imaging apparatus, and image stabilization control method

Abstract

An image stabilization control apparatus corrects image shake, which is caused by the shake of a camera, using a shake correction unit. An angular velocity sensor detects angular rotational shake in the yaw direction, and an angular velocity sensor detects angular rotational shake in the roll direction. An accelerometer detects acceleration in the horizontal direction. A camera CPU calculates a first correction amount for use in the correction of translational shake in the yaw direction using the outputs of the angular velocity sensor and the accelerometer, and calculates a second correction amount for use in the correction of translational shake in the roll direction using the outputs of the angular velocity sensor and the accelerometer. A driving unit drives a shake correction unit in accordance with the correction amount of translational shake.
