    Abstract: A displacement sensor includes a first frame; a second frame; a first coil including a first voltage formed at the first frame applied to the first coil; a second coil formed at the first frame including a current of a second voltage flowing in the second coil corresponding to a voltage of the first frame if the first voltage is applied to the first coil; a conductor coupled to the second frame; and a detector for calculating a relative position between the first frame and the second frame by monitoring the second voltage. Further, a size of the second voltage is reduced if the second coil is moved closer to the conductor.

    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.

    Abstract: A camera for an electronic device, which is compact and exerts high performance is disclosed. The camera for an electronic device includes a housing, a lens assembly mounted movably inside the housing, an actuator configured to move the lens assembly relative to the housing, and a guide provided in the lens assembly and the housing, and configured to guide the relative movement of the lens assembly. The guide includes a first guide configured to support a first surface of the lens assembly with respect to the housing, for the relative movement of the lens assembly, and a second guide configured to support a second surface of the lens assembly, different from the first surface, with respect to the housing, for the relative movement of the lens assembly.

    Abstract: Disclosed is a camera module capable of overcoming a design limitation on a structure for auto-focusing and handshake compensation attributable to the thickness of the camera module provided in a small-sized camera device. The camera module includes a refractive unit including at least one lens, which has an optical axis oriented in a first direction, a lens case for supporting the refractive unit mounted thereto, a focusing-driving magnet secured to the lens case, a focusing-driving coil configured to accommodate at least a portion of the focusing-driving magnet inserted thereinto and to receive first current and generate driving force for allowing the focusing-driving magnet to perform first relative displacement in the first direction, a compensatory case configured to support the focusing-driving coil fixedly mounted thereto, and a focusing-sensing coil fixedly provided in the compensatory case and wherein second current is electromagnetically induced at the focusing-sensing coil by the first relative displacement.
