Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a continuation application, claiming priority under 35 U.S.C. § 365(c), of an International application No. PCT/KR2024/009198, filed on Jul. 1, 2024, which is based on and claims the benefit of a Korean patent application number 10-2023-0083979, filed on Jun. 29, 2023, in the Korean Intellectual Property Office, and of a Korean patent application number 10-2023-0148577, filed on Oct. 31, 2023, in the Korean Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety. BACKGROUND 1. Field The disclosure relates to a camera module and an electronic device including the same. 2. Description of Related Art Along with the advancement of digital camera manufacturing technology, electronic devices equipped with small, lightweight camera modules have become commercialized. As camera modules are now included in electronic devices (e.g., mobile communication terminals) that people always carry, users may easily use various functions such as taking photos and videos, making video calls, or using augmented reality. Typically, a camera module may be configured to include a lens assembly and an image sensor. The camera module may perform image stabilization function to correct for external disturbances. An external disturbance may be an artifact like image blur caused by slight hand tremors, when a user takes a picture or records a video. Image stabilization function, such as an anti-shake (or hand-shake) correction function, may prevent or mitigate shaking in a captured image or video by moving the lens assembly or image sensor included in the camera module on a plane perpendicular to an optical axis to compensate for the limited movement of an electronic device caused by its being held by a fixing device or the user's grip. For this purpose, the camera module may include at least one coil and a magnet. When current is applied to the coil, it may generate an electromagnetic force through electromagnetic interaction with the magnet, and the camera module may then use the generated electromagnetic force to perform the anti-shake correction function. Various methods may be applied to correct for shaking using an electromagnetic force, such as lens shift for moving the lens assembly, image sensor shift for moving the image sensor, prism shift for moving a prism, and module tilt for tilting the camera module. The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
