Description

[Technical Field]

[0001] The present invention relates to a camera actuator and a camera module including the same. [Background technology]

[0002] A camera is a device that takes pictures or videos of objects and can be used in handheld devices, drones, and vehicles. The camera module detects the movement of the user to improve the quality of the image. Image Stabilization to correct or prevent image shake caused by tion, IS) function, which automatically adjusts the distance between the image sensor and the lens to focus the lens. Auto Focusing (AF) function to align distance, zoom The zoom lens increases or decreases the magnification of distant objects. It may have a zooming function for taking pictures.

[0003] On the other hand, the higher the pixel count of an image sensor, the higher the resolution and the larger the pixel size. The smaller the pixel, the less light it can receive in the same amount of time. Therefore, the higher the pixel count of the camera, the slower the shutter speed will be in a dark environment. This can make the image blur caused by camera shake even more pronounced. Image Stabilization (IS) A representative example of this technology is a technology that compensates for movement by changing the path of light. Optical image stabilization (OIS) ) technology is available.

[0004] In general OIS technology, the camera uses a gyro sensor, etc. It senses camera movement and tilts or moves the lens based on the sensed movement. Tilting or moving the camera module, which includes the lens and image sensor. The camera module, which includes a lens or a lens and an image sensor, is OIS. When tilting or moving the camera, tilting around the lens or camera module Or additional space for movement needs to be secured.

[0005] On the other hand, the actuator for the OIS can be placed around the lens. The actuator for this is the X-axis tilting, which is perpendicular to the optical axis Z. It can include an actuator responsible for Y-axis tilting and an actuator responsible for Y-axis tilting. do.

[0006] However, the need for ultra-slim and ultra-compact camera modules has led to the need for OIS. There are significant spatial restrictions on the placement of the actuator, and the lens or the lens and image sensor The camera module itself, including the sensor, has enough space to be tilted or moved for OIS. In addition, the higher the pixel count of the camera, the more light is received, so the It is preferable to increase the lens size for this purpose, but the actuator for the OIS takes up a large area. There may be a limit to how large the lens can be due to available space.

[0007] In addition, the camera module includes zooming, AF, and OIS functions. When using the OIS, the magnet for OIS and the magnet for AF or Zoom must be placed close to each other. There is also the problem of magnetic field interference due to the placement of the device. Summary of the Invention [Problem to be solved by the invention]

The structure 1232 may include, but is not limited to, a reflective portion disposed therein. The prism 1232 is not a mirror. It reflects light from the outside (for example, an object) and In other words, the prism 1232 reflects the light. The optical path is changed to spatially locate the first and second camera actuators. This allows the camera module to be minimized in thickness while still achieving the maximum possible image quality. It should be understood that the light path can be extended to provide a higher range of magnification.

[0147] Furthermore, the first member 1231a can be coupled to the prism holder 1231. The member 1231a is a prism holder 1231, and is a part of the outer surface of the fourth prism other than the fourth mounting groove. The first member 1231a can contact the protrusions located in the prism holder 123. Alternatively, the first member 1231a may be separate from the prism holder 1231. The structure may be formed as follows.

Specifically, in the first embodiment, the tilting guide part 1241 is The mover 1230 and the housing are disposed between the first member 1231a and the second member 1226. Accordingly, the fourth housing 1220 can be connected to the third direction (Z-axis direction). The tilting guide portion 1241 is a first member 1231a. The tilting guide portion 1241 is a second member 1231b. 226 and a prism holder 1231 may be arranged in this order.

[0150] In addition, the tilting guide portion 1241 can be disposed adjacent to the optical axis. The actuator according to the embodiment facilitates changing the optical path by tilting along the first and second axes, which will be described later. It can be easily accomplished.

The repulsive force is generated between the prism holder 1231 coupled to the first magnetic body 1242 and the second magnetic body 1243. The second member 1226 may be attached to the body 1243 or the housing 1220. Therefore, the repulsive force applied to the prism holder 1231 can also be transmitted to the first member 1231a. As a result, the tilting guard disposed between the first member 1231a and the second member 1226 The tilt guide portion 1241 can be pressed by the repulsive force. 241 can maintain the force between the first member 1231a and the second member 1226. This will be explained in more detail later.
