Title:
ELECTRONIC DEVICE COMPRISING CAMERA, AND METHOD FOR OPERATING ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/215943
Kind Code:
A1
Abstract:
An electronic device according to one embodiment of the present invention comprises: a housing including an OIS coil and an AF coil; a first lens disposed in the housing along an optical axis, a second lens disposed under the first lens, and a third lens disposed under the second lens, wherein the second lens changes shape according to the position of an AF carrier; an OIS carrier including an OIS magnet at a position corresponding to the OIS coil of the housing to move the third lens in a direction perpendicular to the optical axis; the AF carrier that is coupled onto the OIS carrier and includes an AF magnet at a position corresponding to the AF coil of the housing in order to move the second lens in the optical axis direction; and a processor electrically connected to the OIS coil and the AF coil. The processor can control the current applied to the OIS coil and thereby move at least the third lens in a direction perpendicular to the optical axis by using the OIS carrier, and control the current applied to the AF coil and thereby change the shape of the second lens using the AF carrier. According to various embodiments of the present invention, AF is performed using only a portion of the lenses, such that it is not necessary to secure separate space for performing AF, and thus space efficiency can be increased. Also, since the lenses do not move as a unit, the size of a camera module can be reduced. Furthermore, since AF is performed using only a portion of the lenses, current consumption can be reduced. Various other embodiments are possible.
