Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an anti-shake device and a mobile phone including the anti-shake device. [Prior Art 3 [〇〇〇2] With the development of technology, the image capture module has become more and more miniaturized, and it can also be installed on portable devices such as mobile phones, personal digital assistants, and notebook computers. It has portability. However, the portable device in which the small image capturing device is located is also small in size. Therefore, when the user uses the shutter, it is easy to cause the jitter of the portable device when the shutter is pressed, so that the image captured by the image capturing device is blurred β. [〇〇〇3] There are two ways to solve the body shake by using the crane. It is generally applied to Yao·Volume Camera or Digital Camera. One is to reduce the probability of body shake by the camera: fixing or adding a stable grip mechanism. For example, the tripod is selected, but since the two-corner frame is cumbersome, it is inconvenient to uncover and place the tape, and the loading and unloading and adjustment are troublesome, and it is not suitable for fast moving shooting. Secondly, the camera can be fixed on the handle by means of the handle, and the south quality shooting activity can be performed by the bracket, and the control of the electronic shutter is located on the index finger of the handle, which is convenient and reliable to use. The handle is based on the soldier's gun shooting principle, which makes the camera more stable and reduces the impact of jitter on the shot. However, it only reduces the occurrence of camera shake, and does not reduce the effect of jitter on the quality of the captured image, and cannot achieve the purpose of shooting higher quality images. 098126652 In addition, it is also possible to move the compensation lens group to eliminate the influence of the main lens module jitter, but this also expands the imaging range. Form number Α0101 Page 4/15 pages 0982045669-0 [0004] 201106008 Since a set of compensating lens groups is added, the volume of the camera module or the lens barrel is also increased at the same time, which is unfavorable for carrying, and thus is not suitable for small or miniature shooting devices.
