    Abstract: The present invention relates to an apparatus and a method for controlling auto focus of a camera module including a voice coil motor actuator. The camera module includes a sensing unit configured to sense a movement of the lens unit and a controller configured to control the movement of the lens unit based on a sensing signal sensed by the sensing unit. If an initial operation command is received, the controller moves the lens unit to an end point of a maximum movement range. If the lens unit is positioned at the end point of the maximum movement range, the controller compares the sensing signal sensed by the sensing unit with a predetermined reference signal to calculate a compensation value for an error. If a focus operation command is received, the controller can move the lens unit to a focus position based on the calculated compensation value and compensate for the focus position of the lens unit.

    Abstract: A dual camera module that includes a voice coil motor actuator and a method for controlling the same are disclosed. The dual camera module comprises a first camera including a first lens module; a second camera including a second lens module, arranged to adjoin the first camera; and a controller for controlling the first camera and the second camera, wherein the controller identifies whether the first camera includes a first sensing module for sensing movement of the first lens module if a camera execution command is received, identifies whether the second camera includes a second sensing module for sensing movement of the second lens module if the first camera includes the first sensing module, identifies whether the first sensing module of the first camera and the second sensing module of the second camera have the same type as each other if the second camera includes the second sensing module, and controls the first camera and the second camera at different time zones if the first sensing module and the second sensing module have the same types as each other.

    Abstract: Disclosed is an image acquiring device, including a liquid lens having a shape changed by pressurization, a membrane provided to one surface of the liquid lens, the membrane forming a pressurization surface, a pressurizing member provided to an outside of the membrane, and a support wire provided across a prescribed region of an outer surface of the pressurizing member, the support wire moving the pressurizing member toward the membrane by contracting by conduction, the support wire moving the pressurizing member toward an opposite side of the membrane by expanding. Accordingly, the present invention solves a problem of a mismatched focus in a close-up photo and minimizes an increasing volume of the image acquiring device.
