<p>PURPOSE:To restrain a current wasted in a camera shake correction controller by transferring serial data between a master controller and a camera shake correction controller and switching the standby state and the acting state of the camera shake correction controller. CONSTITUTION:When power is supplied to an A microcomputer 1 being the master controller, the reset releasing processing of a B microcomputer 2 being the camera shake correction controller is performed, and the microcomputer 2 stands by for a specified time. Correction lens reset instructing processing that a camera shake correction lens 17 is driven to a reset position is serially communicated from the microcomputer 1 to the microcomputer 2. Next, standby transition instructing processing that the microcomputer 2 is made to a standby state from an acting state is serially communicated from the microcomputer 1 to the microcomputer 2. Thus, the power supply processing of the microcomputer 1 is finished. Namely, when the power is supplied, the microcomputer 1 releases the microcomputer 2 from the reset state, and the microcomputer 1 makes the microcomputer 2 to the standby state from the acting state through serial communication after the specified processing is finished.</p> |
