Abstract

An embodiment of the present invention discloses a camera actuator comprising: a housing; a mover disposed in the housing and including, on one surface thereof, a boss protruding toward the housing; the driving unit is arranged in the shell and enables the mover to rotate in a first direction or a second direction perpendicular to the first direction, the bosses comprise a first boss arranged on one surface, a second boss spaced from the first boss, and a third boss, and the spacing distance between the third boss and the first boss is larger than that between the third boss and the second boss; the shell comprises a groove where the first boss is located, a first hole where the second boss penetrates and a second hole where the third boss penetrates in the inner surface corresponding to the surface, the side surface of the second boss is separated from the first hole, and the side surface of the third boss is separated from the second hole. And the shell comprises a protrusion which is arranged on the side surface of the second hole and extends towards the third boss.

Description

technical field [0001] The present invention relates to a camera actuator and a camera module including the camera actuator. Background technique [0002] Cameras are devices that capture pictures or videos of objects, and are mounted on portable devices, drones, vehicles, and the like. To improve image quality, the camera module has: Image Stabilization (IS) function, which corrects or prevents image shake due to user's motion; Auto Focus (AF) function, which automatically adjusts the distance between the image sensor and the lens to adjust the focal length of the lens ; and the zoom function, which increases or decreases the magnification of distant objects through the zoom lens. [0003] Meanwhile, in the image sensor, the resolution becomes larger as the number of pixels becomes higher, and thus the size of the pixel is reduced. As pixels get smaller, the amount of light received at the same time decreases. Therefore, when the camera has a higher pixel count, the shak...
