<p>PURPOSE:To restrain a current consumed in a shake detecting device and a driving device even when abnormality in serial data communication is found by employing the constitution so that a shake correction controller cuts off power supply to the shake detecting device and the driving device in the case the shake correction controller detects the abnormality in the serial data communication. CONSTITUTION:A B microcomputer 2 being the shake correction control circuit is a sub microcomputer executing shake restraining control, and shake detection circuits 9 and 10, motor driving circuits 11 and 12, and lens position detecting circuits 19 and 20 are connected to the microcomputer 2. A motor 13 driving a shake correction lens 17 in an X-axis direction is connected to the motor driving circuit 11 being the driving device, and a motor 14 driving the lens 17 in a Y-axis direction is connected to the motor driving circuit 12 being the driving device. In such constitution, when the microcomputer 2 detects the abnormality in the serial data communication, it cuts off the power supply to the detecting circuits 9 and 10 and the driving circuits 11 and 12.</p> |
