Abstract

A lens module of an embodiment comprises: a lens having a cavity for containing a fluid; a first mover frame supporting the lens and comprising a pressing portion disposed to face a pressing area of the fluid; a magnet disposed at the first mover frame; a coil portion comprising a coil disposed to face the magnet in a first direction perpendicular to an optical axis; a second mover frame which isdisposed to face the first mover frame in a second direction parallel to the optical axis with the magnet placed therebetween, and supports the magnet together with the first mover frame; and a driving control portion which supplies an electric current to the coil to make the coil and the magnet interact with each other, and thereby controls the pressing portion of the first mover frame to press apressing area of the lens.

Description

technical field [0001] Embodiments relate to a lens module and a camera module including the same. Background technique [0002] People who use portable devices require optical devices that have high resolution, are compact, and have various photographing functions. For example, these various photographing functions may be at least one of an optical zoom in / out function, an auto focus (AF) function, hand shake compensation, or an optical image stabilization (OIS) function. [0003] In conventional techniques, in order to realize the above-mentioned various photographing functions, a method of combining a plurality of lenses and directly moving the combined lenses is used. However, in the case of increasing the number of lenses, the size of the optical device increases. [0004] Auto focus and hand shake compensation functions are performed by moving or tilting a plurality of lenses fixed to the lens holder and aligned along the optical axis in the direction of the optical ...
