Claim:
1. An optical image stabilizer comprising: a motion sensor configured to sense a movement of a camera; a controller configured to move a lens module based on the movement of the camera; a communicator configured to communicate with a host; and a power manager configured to control a power supply of the optical image stabilizer and to turn on only the communicator in the standby mode, wherein the optical image stabilizer enters a standby mode based on an optical image stabilization (OIS) turn-off command being received from the host, in response to the camera being turned off or a camera function being executed in a background during a stage in which an OIS operation is performed, and wherein the power manager is further configured to back up an operation frequency and power related set values before the optical image stabilizer enters the standby mode, and to decrease the operation frequency to be sufficient for operation of the communicator.
