201114249 六、發明說明： 【發明所屬之技術領域】 [0001] 本發明涉及光學防抖技術，尤其涉及一種能夠光學防抖 的影像穩定模組及具有該影像穩定模組的成像裝置。 【先前技術】 [0002] 隨著數碼相機技術不斷發展，相機的機身往往既小且輕 ，容易因使用者手震而造成相機的抖動，導致相機成像 模糊。因此，現今的數碼相機中通常加入了防手震技術 以克服成像模糊的問題。 [0003] 目前’應用於數碼相機中的防手震技術主要分為兩種： 一種係使影像感測器在與鏡頭光軸垂直的平面中運動與 相機機身的抖動量對應的量來減少相機的成像模糊；另 一種係移動鏡碩系統中的鏡片來補償相機機身的抖動量 。此兩種防手震技術均採用可移動單元、支撐並移動該 可移動單元的固定單元以及固定在機身上且用於檢測相 機機身抖動量的角速度感測莽。該可移動單元與影像感 ... ! ：. .· 測器或鏡片固定並根據角速度鼠測器檢測到的抖動量運 動，從而減少成像模糊。 [0004] 一般地，角迷度感測器係安裝在獨立於可移動單元和固 定單元的主基板上，且主基板的位置與影像感測器或鏡 頭系統有一定距離。為了減小相機重量，主基板通常报 薄，當機身抖動時，主基板很容易彎曲。因此，移動單 元中影像感測器或鏡片實際的抖動量與角速度感測器檢 測到的抖動量會不同，從而影響防手震的準碟性。 【發明内容】

Description of the Invention: [Technical Field] The present invention relates to an optical image stabilization technology, and more particularly to an image stabilization module capable of optical image stabilization and an imaging device having the image stabilization module. [Prior Art] [0002] With the continuous development of digital camera technology, the camera body is often small and light, and it is easy to cause camera shake due to user's hand shake, resulting in camera blur. Therefore, anti-shake technology is often added to today's digital cameras to overcome the problem of image blur. [0003] At present, the anti-shake technology applied to digital cameras is mainly divided into two types: one is to reduce the amount of motion of the image sensor in a plane perpendicular to the optical axis of the lens corresponding to the amount of jitter of the camera body. The imaging of the camera is blurred; the other is to move the lens in the mirror system to compensate for the amount of jitter in the camera body. Both of these anti-shake techniques employ a movable unit, a fixed unit that supports and moves the movable unit, and an angular velocity sensing unit that is fixed to the body and used to detect the amount of camera body shake. The movable unit and the image sense are fixed by the detector or the lens and are moved according to the amount of jitter detected by the angular velocity mouse, thereby reducing imaging blur. [0004] Generally, an angular saliency sensor is mounted on a main substrate that is independent of the movable unit and the fixed unit, and the position of the main substrate is at a distance from the image sensor or lens system. In order to reduce the weight of the camera, the main substrate is usually thinned, and when the body is shaken, the main substrate is easily bent. Therefore, the actual amount of jitter of the image sensor or lens in the moving unit is different from the amount of jitter detected by the angular velocity sensor, thereby affecting the quasi-disc nature of anti-shake.

The N-pole to S-pole closed magnetic field is subjected to a downward force, that is, a force substantially in the negative direction of the Z-axis. The first lower side 322b is also subjected to a downward force in the closed magnetic field of the first lower permanent magnet 342b from the N pole to the S pole.

The optical axis of the lens module 20A is aligned with the image sensor 300 and aligned with the center of the light entrance hole 23a of the upper surface 23 of the movable frame 2. When the imaging device 2 is shaken, the movable frame 20 of the image stabilization module 100 drives the lens module 2 and the image sensor 300 to perform shake compensation. Preferably, the lens module 200 employs an autofocus lens module, such as the lens 200a disposed in the movable chrome barrel of the voice coil motor actuator. The invention provides an imaging device with a 彡 image module, and is provided with a rotatable device for accommodating a lens module and an image sensory sensation in the truss and the hearing sensing (four) In the movable frame, the amount of jitter of the movable frame, the mirror group and the image phase device can be detected by the ball, thereby improving the accuracy of the anti-shake. In summary, this issue (4) has met the requirements of the invention patent, and the patent is requested in accordance with the law. However, the above is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case.
