  • Publication number: 20110122267
    Abstract: A shake correction module, a camera module including the same, and a method of manufacturing the camera module are provided. The shake correction module includes: a hinge member which supports rotation movement of an optical module based on each of at least two axes at least by using an elastic characteristic of the hinge member, wherein the optical module comprises an image sensor; a base member to which the hinge member is installed; and a driving motor which rotates the hinge member based on the each of the at least two axes with respect to the base member, in order to manufacture a structure for supporting two-axes rotation of the optical module to be simple and reliable with a low manufacturing cost.

  • Patent number: 7907839
    Abstract: An image photographing device including a lens holder including a lens group and a coil unit that generates an electromagnetic force, a housing into which the lens holder is movably inserted, including a magnet that faces the coil unit, an image sensor, and a diaphragm formed of nonmetal and attached to the housing and elastically supporting the lens holder. Accordingly, the diaphragm has a predetermined elasticity although not reducing the thickness, the lens holder can properly follow the signal of the coil unit, the image photographing device is highly producible, and the possibility that the diaphragm is plastically deformed is small. Also, the terminal of the coil unit is connected to a separate terminal unit installed outside the diaphragm, such that the material used to form the diaphragm can be selected regardless of the conductivity, and foreign materials, such as, flux, can be prevented from contaminating the inside of the device and degrading the quality of an image.
