Description of the Invention: [Technical Field] The present invention relates to optical image stabilization technology, and more particularly to a camera module capable of optical image stabilization. [Prior Art] [〇〇〇2] The camera module controls the length of time the light is projected onto the image sensor by the shutter. For example, when the shutter speed is 1/2 second, the image sensor is sensitive to 1/1. 2 seconds, if the same beam of light moves on the image sensor due to the jitter within 1/2 second, the image sensor will record the motion track of the light' to blur the photo taken. . In order to compensate for the amount of light offset caused by jitter, a camera module using an image stabilization system to prevent jitter was introduced in the 1990s. For details, please refer to Cardani B. et al. April 2006 at Control Systems

之振幅放大，輕微之抖動亦會造成較大之模糊，因此手 部震動對畫面清晰度之影響較使用廣角鏡頭明顯；二， 弱光環境拍攝，於室内、黃昏等弱光源環境，相機會將 快門速度調得較慢以增加入光量’因此較易發生手震； 二’微距拍攝’細微物件於鏡頭高倍放大之情況下，輕 微震動亦會變得相當明顯。這些情況均可以造成手震， 098126651 表單編號A0101 第4頁/共32頁 0982045668-0

[〇〇〇3] With the continuous development of digital camera technology, the camera body is often small and light ‘easy to cause jitter, resulting in blurred images. The following three situations are prone to blurry images··- 'Long focal length shooting, because the long lens will magnify the amplitude of the camera, slight jitter will also cause a large blur, so the impact of hand vibration on the sharpness of the picture is better than using a wide-angle lens Obviously; Second, shooting in low light environment, in indoor, dusk and other weak light source environment, the camera will adjust the shutter speed to be slower to increase the amount of light entering' so it is more prone to jitter; 2 'Macro shot' fine objects in the lens high When zoomed in, the slight vibration will become quite noticeable. These conditions can cause jitter, 098126651 Form No. A0101 Page 4 of 32 0982045668-0 201106007 Makes the image blurred. Since the distance of the object photographed by m. is much larger than the displacement of the camera's light movement, the main reason for the blurring of the image is the deflection of the camera itself, not the displacement of the camera itself, especially the far moment. This situation is particularly severe when shooting.
