Abstract

The camera module or camera device according to the embodiment may include a base, a first lens assembly and a second lens assembly disposed and moved within the base, and a third lens assembly disposed and fixed to the base. The first lens assembly includes a first lens barrel in which a first lens is disposed, and a first driver housing in which a first driving part is disposed, and the second lens assembly comprises a second lens barrel in which a second lens is disposed. The second driving part housing may include a second driving part. The base may include a base stopper that limits strokes of the first lens assembly and the second lens assembly. The lens housing of the third lens assembly may include a barrel stopper to limit strokes of the first lens assembly and the second lens assembly.

Description

technical field [0001] Embodiments relate to a camera module and a camera device including the camera module. Background technique [0002] The camera module performs a function of photographing a subject and storing it as an image or a moving image, and is mounted on a mobile terminal such as a mobile phone, a laptop, a drone, a vehicle, and the like. [0003] Meanwhile, ultra-small camera modules are built into portable devices such as smartphones, tablet PCs, and notebook computers, and such camera modules can perform an autofocus (AF) function that automatically adjusts the distance between the image sensor and the lens. distance to adjust the focal length of the lens. [0004] In addition, recently, a camera module may perform a zoom function that enlarges or reduces a photographic subject by increasing or decreasing a magnification of a distant subject by means of a zoom lens. [0005] Also, recently, camera modules employ image stabilization (IS) technology to corre...
