Abstract
Description
Technical Field
[0001] This embodiment relates to a driving device, a camera module, and a mobile terminal device.
Background Art
[0002] A camera module performs a function of photographing a subject and storing it as an image or a video, and is mounted on mobile terminals such as mobile phones, notebooks, drones, and vehicles.
[0003] On the other hand, portable devices such as smartphones, tablet PCs, and notebooks have built-in ultra-small camera modules. Such camera modules can perform an autofocus (AF) function of automatically adjusting the distance between an image sensor and a lens to align the focal length of the lens.
[0004] In recent years, camera modules can also perform a zooming function of zooming in (zoom up) or zooming out (zoom out) by increasing or decreasing the magnification of a subject at a long distance through a zoom lens.
[0005] In recent years, camera modules have also adopted an image stabilization (IS) technology to correct or prevent camera shake caused by an unstable fixing device or the movement of a user.
[0006] Such image stabilization (IS) technologies include an optical image stabilizer (OIS) technology and an image stabilization technology using an image sensor.
[0007] OIS technology is a technique that corrects motion by changing the path of light, and image Image stabilization technology using image sensors corrects motion using both mechanical and electronic methods. While both technologies exist, OIS technology is more widely adopted.
[0008] On the other hand, the camera module uses a zoom actuator for the zooming function. It utilizes an actuator, but the mechanical movement of the actuator affects the lens Friction torque is generated during movement, and this friction torque reduces driving force and power consumption. Technical problems such as increased force or degraded control characteristics are occurring.
[0009] In particular, the camera module has multiple zoom lens groups. To achieve the best optical characteristics using this method, the alignment between multiple lens groups is crucial. The alignment between the multiple lens groups and the image sensor should be good, but between the lens groups Decentering, where the center of the sphere deviates from the optical axis, and tilt, a phenomenon where the lens tilts. (tilt) When the central axis of the lens group and the image sensor are not aligned, the image This can cause changes in the angle of focus or loss of focus, negatively impacting image quality and resolution.
[0010] On the other hand, the camera module reduces frictional torque resistance when the lens moves for zooming functionality. To increase the isolation distance in the area where friction occurs, zoom movement or zoom Lens eccentricity and tilt become more severe when the lens motion reverses. Technical problems and inconsistencies have arisen.
[0011] On the other hand, the higher the pixel count of an image sensor, the higher the resolution and the larger the number of pixels. The size decreases, but as the pixels become smaller, the amount of light that can be received in the same amount of time decreases. Therefore, the higher the resolution of the camera, the slower the shutter speed will be in dark environments. The shaking of the hands, which causes the image to waver, becomes more pronounced.
[0012] This allows you to capture distortion-free images using a high-resolution camera in dark nighttime conditions or when shooting videos. For this reason, OIS functionality has become an essential feature in recent years.
[0013] On the other hand, OIS technology moves the camera lens or image sensor to improve the optical path (optical). This method corrects image quality by modifying the image path, but especially OIS technology This is achieved by sensing the camera's movement via a gyro sensor. Based on this, the distance the lens and image sensor should move is calculated.
[0014] For example, OIS correction methods include lens movement methods and modular tilting. There is also the ng method. The lens movement method is used to realign the center of the image sensor with the optical axis. This moves only the lens inside the camera module. On the other hand, module tilting method The formula is a method of moving the entire module, which includes the lens and image sensor.
[0015] In particular, the modular tilting method offers a wider correction range compared to the lens movement method. Since the focal length between the lens and the image sensor is fixed, image distortion It has the advantage of minimizing [the problem].
[0016] On the other hand, in the case of a lens movement system, a position recognition sensor is used to sense the position and movement of the lens. , for example, a hall sensor is used. On the other hand, in the module tilting method, a photo reflector is used to sense the movement of the module. However, in order to sense the movement of the camera user, a gyro sensor is used in both methods. ring method, a photo reflector is used to sense the movement of the module. However, in order to sense the movement of the camera user, a gyro sensor is used in both methods. ring method, a photo reflector is used to sense the movement of the module.
[0017] The OIS controller predicts the position where the lens or module should move to compensate for the movement of the user, and uses the data recognized by the gyro sensor. ring method, a photo reflector is used to sense the movement of the module.
[0018] In recent years, ultra-thin and ultra-small camera modules are required according to technological trends. However, in ultra-small camera modules, there are spatial constraints for OIS driving, and it is difficult to realize the OIS function applied in general large cameras. There is a problem that an ultra-thin and ultra-small camera module cannot be realized when applying OIS driving. ring method, a photo reflector is used to sense the movement of the module. ring method, a photo reflector is used to sense the movement of the module. ring method, a photo reflector is used to sense the movement of the module.
[0019] In addition, in the conventional OIS technology, as the OIS driving unit is arranged on the side of the solid lens assembly within the limited size of the camera module, there is a problem that it is difficult to ensure the light amount due to the size limitation of the lens to be OIS-targeted. ring method, a photo reflector is used to sense the movement of the module. ring method, a photo reflector is used to sense the movement of the module.
[0020] Particularly, in order to achieve the best optical characteristics in a camera module, the alignment between lens groups should be well-matched when realizing OIS through lens movement or module tilting. However, in the conventional OIS technology, problems occur such as the change of the angle of view and the occurrence of focus deviation when eccentricity (decent) where the spherical center between lens groups deviates from the optical axis or tilt (tilt) which is a lens tilt phenomenon occur, which have an adverse effect on image quality and resolution. ring method, a photo reflector is used to sense the movement of the module. ring method, a photo reflector is used to sense the movement of the module. ring method, a photo reflector is used to sense the movement of the module. ring method, a photo reflector is used to sense the movement of the module.
[0021] Furthermore, conventional OIS technology allows for simultaneous OIS operation with autofocus or zooming. However, due to the spatial constraints of the camera module and the position of the drive unit in conventional OIS technology, the OIS... The magnet and the AF or zoom magnet are positioned in close proximity to cause magnetic field interference. This prevents OIS drive from functioning correctly, resulting in eccentricity and tilt phenomena. There are problems that can arise.
[0022] Furthermore, conventional OIS technology uses mechanical drive for lens movement and module tilting. Because it requires a moving mechanism, it has the problem of a complex structure and high power consumption.
[0023] With the widespread adoption of various mobile devices and the normalization of wireless internet services... As this trend continues, consumer demands related to mobile devices have also diversified, and a wide variety of additional devices have emerged for mobile devices. It is attached to the end.
[0024] Among them, a representative example is the camera module that takes photos and videos of subjects. Recently, camera modules attached to mobile devices have image stabilization (image stabilization). By employing lization (IS) technology, it can be affected by unstable fixed devices or user movements. This technology is employed to correct or prevent camera shake caused by movement. Image stabilization (IS) technologies include optical image stabilization. Image stabilization technologies using stabilizer (OIS) and image sensors, etc. There is.
[0025] OIS technology is a technique that corrects motion by changing the path of light, and image Image stabilization technology using image sensors corrects motion using both mechanical and electronic methods. It is a technology, and OIS technology is being adopted more and more.
[0026] On the other hand, the OIS correction method realigns the center and optical axis of the image sensor with the camera's optical axis. A lens movement method that moves only the lens within the joule, and a method that moves the lens and image sensor There is a modular tilting method that allows the modules to move together.
[0027] In the case of a lens-movement system, the greater the angle at which the camera is tilted, the more the corrected image will differ from the original. There is a problem that will lead to this.
[0028] Furthermore, in recent years, there has been a demand for ultra-slim, ultra-compact camera modules in line with technological trends, In the small camera module, the space required for module tilting type OIS drive There are limitations and problems.
