Description
Technical Field
The utility model relates to a camera module technical field especially relates to an anti-shake focuses motor and uses module thereof.
Background
In recent years, small-sized mobile devices with shooting functions are quite popular, and the application range is also continuously expanded, wherein the small-sized mobile devices comprise smart phones, smart glasses, sports cameras, law enforcement recorders and automobile data recorders. The device comprises at least one zoom (zoom), auto-Focus (Auto-Focus) or Fixed-Focus (Fixed-Focus) miniature camera module. Therefore, the market of the module is huge, and the growth is steadily promoted.
When taking pictures and films, the pictures and films taken by the device are likely to appear blurred or swayed due to external vibration, which affects the quality of the pictures and films. This problem is exacerbated when the vibrations are relatively intense, or in low light conditions.
In order to solve the above problems, many different anti-shake technologies have appeared on the market. In the existing mainstream technology, the effect of improving image quality is achieved by reading a vibration sensor (such as a gyroscope and an acceleration sensor), calculating a vibration waveform and a required compensation angle, and compensating image blurring and shaking caused by vibration through an electronic, optical or mechanical method.
The related art may be classified into four types according to a vibration compensation method, including Electronic Image Stabilization (EIS), optical Image Stabilization (OIS), translation-Sensor stabilization (SSS), and anti-vibration holder (Gimbal holder, GS). EIS, OIS, SSS and GS have different advantages and disadvantages.
EIS achieves anti-shake effect by electronic means. During shooting, the EIS adjusts the position of each frame of image according to the calculated vibration waveform to counteract the image shake caused by vibration. Since the EIS does not require an additional actuator, the main advantage of the EIS is low cost, without additional weight and volume.
The OIS is an Optical and mechanical method, in which an actuator is used to move an Optical component, so that a relative motion occurs between the Optical component and an Image sensor, and the Optical Path (Optical Path) and the position of an Image Circle (Image Circle) are changed to cancel Image shaking caused by vibration. Since OIS continuously performs optical anti-shake compensation during capturing each frame of image, it can counteract the shaking during exposure of each frame of image, and achieve better image quality than EIS.
The SSS mechanically moves the image sensor using an actuator, so that a relative movement occurs between the optical member and the image sensor, and offsets image shaking caused by vibration. The SSS has the optical anti-shake principle and effect similar to that of OIS, and can counteract the shake during each frame of image exposure, thereby achieving better image quality than EIS. Compared with the OIS, the SSS does not need to move a heavier lens or lens in the anti-shake process, so that the high-frequency anti-shake device has great advantages in terms of high-frequency anti-shake effect and power consumption. In addition, the SSS can compensate for the Roll (Roll) shake that the OIS cannot compensate, and thus can achieve a maximum of 5-axis shake prevention, more than the highest of 4-axis shake prevention of the OIS.
The main stream GS drives the entire camera module including the lens and the image sensor by a mechanical method to make a motion having a direction opposite to the vibration direction but an amplitude close to the vibration direction, so as to cancel the shake caused by the vibration. In the anti-shake process, because there is no relative motion between the optical component and the image sensor, the image quality and the anti-shake effect will not be reduced at the edge of the image, and there is no need to sacrifice the partial optical resolution of the lens and the partial resolution of the image sensor due to the anti-shake. Therefore, the anti-shake effect and image quality of the main stream anti-shake cradle head are better than EIS, OIS and SSS.
In summary, it can be seen that the conventional camera module devices in the market all have respective problems, and the prior art cannot overcome the disadvantages of the conventional camera module devices by integrating the advantages of the camera module devices.
