More Information
Summary: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.
