Description

technical field

[0001] The present invention relates to a lens assembly driving device and a camera module including the lens assembly driving device. Background technique

[0002] The camera module photographs a subject and stores it as an image or video, and the camera module is installed in a mobile terminal such as a mobile phone, a notebook computer, a drone, and a vehicle.

[0003] Meanwhile, portable devices such as smartphones, tablets, and notebooks have built-in ultra-compact camera modules, and such camera modules can perform an autofocus (AF) function that automatically adjusts the distance between the image sensor and the lens to Align the focal length of the lens.

[0004] In addition, recent camera modules are capable of performing a zoom function that zooms in or out by increasing or decreasing the magnification of a distant subject through a zoom lens.

[0005] In addition, recent camera modules employ image stabilization (IS) technology to correct or prev...
