Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] A lens anti-shake device of the present invention, such as figure 1 , figure 2 with image 3 As shown, it includes a Z-axis rotation module 1 and an X-axis rotation module 2 .

[0031] The Z-axis rotation module 1 includes an outer connection frame 11. The X-axis rotation module 2 includes an inner connection frame 21 for connecting with the lens 3. The outer connection frame 11 and the inner connection frame 21 are both rectangular frame structures, so The inner connection frame 21 is connected to the inner side of the outer connection frame 11 and can rotate around the Z axis relative to the outer connection frame 11. The lens 3 is connected to the inner side of the inner connection frame 21 and the lens 3 can rotate around the X axis relative to the inner connection frame 21.

[0032] Such as Figure 4 As shown, the Z-axis rotation modul...

Abstract

The invention discloses a lens anti-shake device, which comprises a Z-axis rotation module and an X-axis rotation module. The Z-axis rotation module rotates around the Z-axis. Both the Z-axis rotation module and the X-axis rotation module are equipped with a rotary piezoelectric motor for correspondingly driving their rotation, and a drive control feedback unit on the rotary drive motor. Through electronic The gyroscope senses the shake of the lens, and sends out a signal to drive the rotation of the rotary piezoelectric motor, and then uses the drive control feedback unit to detect the rotation angle of the rotary piezoelectric motor, and then realizes the corresponding angle compensation for the shake of the entire lens to avoid Shaking affects the shooting quality, ensuring that the camera can take clear and high-quality photos. At the same time, the technical solution of the present invention also has the characteristics of simple structure, small size, quick response, accurate control, low power consumption, and strong anti-electromagnetic interference. .

Description

[0001] 【Technical field】 [0002] The invention relates to a lens, in particular to a lens anti-shake device. [0003] 【Background technique】 [0004] When using a digital camera, many times the pictures captured are not clear enough, and there are phenomena such as ghosting or blurred focus. The reason, in addition to the occasional out of focus, is largely caused by the shutter speed being too low. Generally speaking, when holding a digital camera, shaking is unavoidable. To take a clear picture, you need to increase the shutter speed, and the shutter speed is generally taken as the reciprocal of the focal length or even higher. For example, the telephoto end of some products reaches 370mm, and the shutter speed is required to reach 1 / 400 second, which is generally difficult to achieve. Therefore, it is necessary to carry out anti-shake on the digital camera, and the purpose of anti-shake is to adjust the light path or photosensitive element to compensate the shaking caused...
