Description

[Technical field]

[0001] The present embodiment relates to a drive device, a camera module, and a mobile terminal device. [Background technology]

[0002] The camera module takes pictures of objects and stores them as images or videos. They are installed in mobile devices such as mobile phones, notebooks, drones, vehicles, etc.

[0003] On the other hand, ultra-small mobile devices such as smartphones, tablet PCs, and notebooks The camera module is built in the image sensor. Autofocus (au) automatically adjusts the distance between the lens and the camera to align the focal length of the lens. tofocus,AF) functions can be performed.

[0004] In recent years, camera modules have been used to capture images at long distances via zoom lenses. Zoom up or zoom out to increase or decrease the magnification of the subject. can perform zooming function of zoom out can.

[0005] In recent years, camera modules have become more sensitive to image stabilization. n,IS) technology is used to eliminate camera movement caused by unstable fixtures or user movement. It uses technology to correct or prevent camera shake caused by hand movements.

[0006] Such image stabilization (IS) technology includes optical image stabilization (OIS). Image stabilization technology using optical image stabilizer (OIS) and image sensor There are techniques etc.

[0007] OIS technology is a technology that compensates for movement by changing the path of light, Image stabilization technology using image sensors uses mechanical and electronic methods to correct movement. Although it is a popular technology, OIS technology is more widely adopted.

[0008] Meanwhile, the camera module uses a zoom actuator for the zooming function. The actuator is used to move the lens. Friction torque occurs during movement, and this friction torque reduces the driving force and reduces power consumption. Technical problems such as increased force or reduced control characteristics have arisen.

[0009] In particular, the camera module has multiple zoom lens groups. In order to achieve the best optical performance, the alignment between the multiple lens groups is required. The alignment between the lens groups and the image sensor should be good, but Decentering, which is when the center of the sphere deviates from the optical axis, and tilt, which is when the lens is tilted (tilt) is a phenomenon that occurs when the central axis of the lens group and the image sensor are not aligned. This can result in shifted corners and defocusing, which can adversely affect image quality and resolution.

[0010] Meanwhile, the friction torque resistance during lens movement for zooming function in camera modules is reduced. If you increase the separation distance in areas where friction occurs to make the zoom move or zoom When the lens motion is reversed, lens decentering and tilt become more severe. There are technical issues and inconsistencies.

[0011] On the other hand, the higher the pixel count of an image sensor, the higher the resolution and the larger the pixel size. The size of the pixel is smaller, but 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. The shaking of the image caused by the trembling of the hands becomes more pronounced.

[0012] This allows you to capture distortion-free images using a high-pixel camera in dark nighttime or during video. In recent years, OIS function has become mandatory for this purpose.

[0013] On the other hand, OIS technology moves the camera lens and image sensor to change the optical path. This is a method to correct image quality by modifying the image quality path, especially OIS technology. It detects the camera movement through the gyro sensor. Based on this, the distance that the lens or image sensor should move is calculated.

[0014] For example, the OIS correction method is divided into lens movement method and module tilting method. The lens movement method realigns the center of the image sensor and the optical axis. Only the lens inside the camera module moves. This method involves moving the entire module, including the lens and image sensor.

[0015] In particular, the module tilting method has a wider correction range than the lens movement method. Since the focal length between the lens and the image sensor is fixed, there is no image distortion. This has the advantage of minimizing

[0016] On the other hand, in the case of the lens movement method, a position recognition sensor is used to detect the position and movement of the lens. For example, a hall sensor is used. In the tachometer method, a photoreflector is used to detect the movement of the module. However, both methods detect the movement of the camera user. To do this, a gyro sensor is used.

[0017] The OIS controller detects whether the lens or module is moving to compensate for the user's movements. It predicts the position it should move to using data captured by the gyro sensor.

[0018] In recent years, technological trends have led to demand for ultra-slim, ultra-compact camera modules. The camera module has space limitations for driving the OIS, making it difficult to apply to general large cameras. However, it is difficult to realize the OIS function, and when OIS is applied, it is ultra-slim and ultra-compact. There is a problem in which a camera module cannot be realized.

[0019] In addition, conventional OIS technology requires a solid lens assembly within the limited size of the camera module. The OIS driver is located on the side of the assembly, limiting the size of the lens that is subject to OIS. This makes it difficult to ensure sufficient light.

[0020] In particular, to achieve the best optical characteristics in a camera module, lens movement and module Through tilting, the alignment between the lens groups is well matched when implementing OIS. However, conventional OIS technology has a problem of decentering (decrease) where the center of the spherical surface between lens groups deviates from the optical axis. When the lens tilt occurs, the angle of view changes and the focus shifts. This has resulted in problems such as defects that adversely affect image quality and resolution.

[0021] In addition, with conventional OIS technology, it is possible to achieve AF or Zoom at the same time as driving the OIS. However, due to the spatial constraints of the camera module and the location of the driver in the conventional OIS technology, The magnet and the AF or Zoom magnet are placed close to each other, causing magnetic field interference. This can cause the OIS drive to not work properly, resulting in decentering and tilt phenomena. There is a problem that triggers.

[0022] In addition, conventional OIS technology requires mechanical drive for lens movement and module tilting. However, the need for a driving device results in a complex structure and high power consumption.

[0023] As various mobile terminals have become widespread, wireless Internet services have become commonplace. As the number of mobile terminals increases, consumer demands for mobile terminals become more diverse, and various types of add-on devices are being added to mobile terminals. It is attached at the end.

[0024] A typical example of this is the camera module, which takes photos and videos of the subject. In recent years, the camera modules installed in mobile terminals have become more and more sensitive to image stabilization. lization (IS) technology is adopted to prevent unstable fixation devices or user movement. The technology used is to correct or prevent camera shake caused by camera movement due to the nature of the camera. IS technologies such as optical image stabilization (OIS) Image stabilizer (OIS) technology and image stabilization technology using image sensors There is.

[0025] OIS technology is a technology that compensates for movement by changing the path of light, The anti-shake technology using the camera sensor compensates for movement using mechanical and electronic methods. technology, and OIS technology is being adopted more and more.

[0026] On the other hand, the OIS correction method uses the camera model to realign the center and optical axis of the image sensor. There are two types of lens movement: one in which only the lens inside the module moves, and the other in which the lens and image sensor are moved together. There is a module tilting method that moves them together.

[0027] In the case of the lens movement method, the greater the angle at which the camera is tilted, the more the corrected image differs from the original. There is a problem that this becomes more and more common.

[0028] In addition, in recent years, technological trends have led to demand for ultra-slim, ultra-compact camera modules. In a small camera module, the space required for driving the module tilting type OIS is limited. There is a problem with constraints. Summary of the Invention [Problem to be solved by the invention]
