A folded zoom optical image stabilization (OIS) circuit for driving a prism and a prism actuator, includes an attitude recognition unit configured to recognize housing attitude based on an acceleration sensor value received from an acceleration sensor when an OIS off command is input, and to output housing attitude information, a prism position control unit configured to control a gradual position movement of the prism to a corresponding target position matching the housing attitude information received from the attitude recognition unit, and a prism driving unit configured to move the prism to a target position under a control of the prism position control unit.
