PURPOSE:To restrain a current wasted in a shake correction controller by allowing the shake correction controller to transit from an acting state to a stopping state according to an output signal from a master controller to the shake correction controller by allowing the master controller to use a signal line in the case of detecting abnormality in serial data communication. CONSTITUTION:In the case the master controller detects the abnormality in the serial data communication, it allows the shake correction controller to transit from the acting state to the stopping state according to the output signal to the shake correction controller from the master controller by using the electrically connected signal line. Namely, in the case of supplying the power in the power supply processing of an A microcomputer 1 being the master controller, the microcomputer 1 releases a B microcomputer 2 being the shake correction controller from the reset state. After finishing the specified processing, the microcomputer 1 makes the microcomputer 2 from the acting state to the standby state through the serial communication. |
