Description

[Technical Field] Various embodiments of the disclosure relate to a camera module and an electronic device including the same. [Background 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 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, 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 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 art 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. [Detailed Description of the Invention] [Technical Solution] According to an embodiment of the disclosure, a camera module may be provided. The camera module may include a camera housing, a lens assembly including at least one lens and a lens barrel, a reflection and refraction member supported by the camera housing and configured to change a path of light passing through the lens assembly at least twice, an image sensor, a carrier assembly having a shape at least partially surrounding the reflection and refraction member, a driving member configured to move the carrier assembly in a first direction or in a direction perpendicular to the first direction, or configured to rotate the carrier assembly about the first direction, and a shock alleviator formed on at least one of a portion of the carrier assembly facing the reflection and refraction member or a portion of the reflection and refraction member directed to the carrier assembly. According to an embodiment of the disclosure, a camera module may be provided. The camera module may include a camera housing, a lens assembly including at least one lens and a lens barrel, a reflection and refraction member supported by the camera housing and configured to change a path of light passing through the lens assembly at least twice, an image sensor including an imaging plane directed in the first direction and converting light incident on the imaging plane into an electrical signal, a carrier assembly having a shape at least partially surrounding the reflection and refraction member, and including a first carrier configured to be moved horizontally in at least two directions intersecting each other on a plane perpendicular to the first direction, and a second carrier configured to be moved vertically along the first direction, and a driving member including a magnet disposed on the carrier assembly and a coil disposed at a position corresponding to the magnet, and providing a diving force for the horizontal movement of the first carrier and the vertical movement of the second carrier. A shock alleviator may be formed on at least one of a portion of the carrier assembly facing the reflection and refraction member or a portion of the reflection and refraction member directed to the carrier assembly.
