Abstract

A lens driving device and a camera module including same are provided. A lens driving device includes a lens barrel; a lens disposed in the lens barrel; a plurality of magnets disposed on an external surface of the lens barrel; a guide member coupled to the lens barrel configured to move the lens barrel in an optical axis direction; a first coil disposed on one side of the guide member opposite to one of the plurality of magnets; a base supporting the guide member configured to move the guide member in a direction orthogonal to the optical axis direction; and a second coil disposed on a side wall of the base opposite to a magnet which is not opposite to the first coil.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2015-0051127 filed with the Korean Intellectual Property Office on April 10, 2015, the entire disclosure of which is hereby incorporated by reference for all purposes . technical field [0002] The following description relates to a lens driving device and a camera module including the lens driving device. Background technique [0003] As small camera modules have become multifunctional and compact, applications of small cameras have gradually expanded to mobile devices such as mobile phones, notebook PCs, and tablet PCs. [0004] Generally, a camera module may include: an optical system including a lens; an autofocus device that moves the optical system along an optical axis to control the focal length; an image sensor (such as a CMOS sensor or a CCD sensor) that converts an image obtained by photographing a subject for electrical signals. [0005] In addition, when capturing still ...
