Abstract:
An electronic device according to one embodiment comprises at least one camera module. The camera module comprises a lens housing including, along an optical axis, an image stabilization unit, an autofocus drive unit, a lens system and an image sensor. The image stabilization unit comprises: an optical member for reflecting incident light and emitting the reflected image light at the image sensor; an optical member holder in which the optical member is disposed, and which is arranged to be rotatable around a pitching axis and a yawing axis; a pitching drive unit disposed within the lens housing so as to provide force for rotating the optical member holder around the pitching axis; a yawing drive unit disposed within the lens housing so as to provide force for rotating the optical member holder around the yawing axis; and a centering unit disposed between the lens housing and the optical member holder so as to provide centering force of the optical member holder. The centering unit includes: a centering magnetic which is disposed on the optical member holder and includes a first surface facing a first direction and a second surface facing the direction opposite to the first direction, the second surface being formed in a curved shape; and a centering yoke which is disposed in the lens housing, is arranged to face the second surface while spaced apart from the second surface, and is parallel to the first surface.
