Description

Camera lens anti-shake device

Technical Field

The utility model relates to an anti-shake equipment technical field specifically is a camera lens anti-shake device.

Background

With the development of technology, image capturing modules are becoming more and more miniaturized, and are also portable because they can be installed in mobile phones, pdas, notebooks and other portable devices. However, the portable device in which the small image capturing device is installed is also small and exquisite, so that when a consumer presses the shutter, the portable device is easily shaken when the consumer uses the device, and the image captured by the image capturing device is blurred. When the camera module with focusing and anti-shake functions adopts the structure of the suspension wire, the anti-shake device is usually located below the focusing device and connected through four elastic suspension wires. Under the condition of shooting without shaking, the focusing device drives the lens module to move along the direction of the optical axis of the lens module so as to shoot a clear image. In the case of shake, the lens may slightly move in the X-axis direction or the Y-axis direction, and the anti-shake apparatus drives the focusing apparatus to move in the X-axis direction or the Y-axis direction to compensate for the shake amount during shake compensation. The amount of jitter is detected by a gyroscope mounted on the electronic product or the camera module. In addition, the anti-shake apparatus is further provided with a hall sensor for detecting a magnetic variation during shake compensation and feeding back the detected magnetic variation to the controller, and the controller controls the current of the anti-shake coil according to the magnetic variation to finally reach a predetermined compensation movement amount. One is to fix the camera or add a stable holding mechanism to reduce the occurrence probability of the shake of the camera body. For example, a tripod is selected, but the tripod is heavy, inconvenient to carry and place, troublesome to assemble, disassemble and adjust, and not suitable for fast moving shooting. Secondly, the camera can be fixed on the handle by the aid of the handle, high-quality shooting activities can be carried out by the aid of the bracket, and the electronic shutter is controlled to be located at the index finger position of the handle, so that the camera is convenient and reliable to use. The handle enables the camera to have higher stability according to the gun-holding shooting principle of soldiers, and the influence of shaking on shooting can be reduced. However, the method only reduces the occurrence of camera shake, cannot reduce the influence of the camera shake on the quality of the shot image, and cannot achieve the purpose of shooting the image with higher quality.

In the prior art, a plurality of lens anti-shake devices can prevent the shake of the lens and make the shot image clearer, but the lens anti-shake devices are complex in structure and high in manufacturing cost, and cause great burden to consumers.
