Abstract

The camera module includes: a first driving unit including a rotating plate provided in a housing to be rotatable about an optical axis, and a first shape memory alloy (SMA) wire configured to rotate the rotating plate in response to a first applied current; and an optical module disposed in the housing and coupled to the rotating plate.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2020-0158434 filed in the Korean Intellectual Property Office on Nov. 24, 2020, the entire disclosure of which is incorporated herein by reference for for all purposes. technical field [0003] The following description relates to a camera module and, for example, a camera actuator configured to generate a driving force using the property of a shape memory alloy (SMA) to return to its original shape when heated. Background technique [0004] Camera modules provided in mobile devices are manufactured to have a performance level comparable to that of conventional cameras. In particular, as the frequency of capturing images using mobile devices increases, the demand for camera modules capable of providing high zoom magnification increases. [0005] In the related art, a voice coil motor including a combination of a magnet and a coil is ...
