Abstract:
A camera module according to an embodiment of the present invention comprises: a barrel in which a lens is provided; and a housing having a hollow portion raised to an optical axis direction in which the barrel is inserted to the hollow portion, wherein a diameter of the barrel can be changed at least twice. According to an embodiment of the present invention, a clear image, like an initial stage of the camera module, can be taken even though the frequency of use of the camera module increases.
Abstract:
PURPOSE: A camera module is provided to automatically adjust the focus of a plurality of lenses arranged on both sides of a camera module with a single actuator. CONSTITUTION: A camera module(100) comprises a housing unit, a driving member, a guide holder, and a plurality of lens barrels(40,50). A guide hole is formed inside the housing unit. The driving member is mounted in one side of the housing unit. The guide holder is received in the guide hole of the housing unit and moved by the driving member. The lens barrels, which are mounted in both sides of the guide holder respectively, include one or more lenses(41,51).
Abstract:
PURPOSE: A camera module having an automatic focusing device is provided to rapidly and exactly catch a focus by controlling a drive of a piezoelectric actuator and sensing a position of a lens barrel including a feedback system. CONSTITUTION: A camera module having an automatic focusing device comprises a piezoelectric actuator(110), a rod(120), a lens barrel(150), and a connection member(140). The piezoelectric actuator generates a moving force of a driven body. The rod is connected to the piezoelectric actuator. The rod transfers the moving force of the piezoelectric actuator and consists of a magnetic. The lens barrel comprises one or more lens. The connection member joins the rod and lens barrel by a magnetic force and consists of a magnetic.

Abstract:
PURPOSE: A lens actuating module is provided to apply pressure to a lens by using the repulsion of magnet without the contact between a lens barer and a drive member. CONSTITUTION: A lens actuating module comprises a housing(110), a lens barrel(120), a driving member, a base magnet(140) and a lens magnet(150). The accommodation space is formed in the housing. The lens barrel is accepted to the accommodation space. The lens barrel comprises a lens. The driving member is installed in one side of the accommodation space in an optical axis direction. The driving member transfers the lens barrel. The base magnet is installed in the other side of the accommodation space. The lens magnet is installed in the exterior of the lens barrel, with faced to the base magnet, in order to generate repulsion.
Abstract:
PURPOSE: A hand shaking correction device of a camera module is provided to simplify a structure by reducing the number of components and increase the reliability of the product for transmitting driving force. CONSTITUTION: A moving stage(300) receives a lens barrel to the inside. The moving stage includes a magnet(360). A piezoelectric actuator(400) is installed to a base member(200). The piezoelectric actuator moves the moving stage to an x-direction and y-direction. The piezoelectric actuator maintains the contact state with the moving stage by the magnetic force.
