Problems solved by technology

[0003] With the continuous development of digital camera technology, the body of the camera is often small and light, which is easy to cause hand shake, resulting in blurred images
The following three situations are likely to produce blurred images: 1. When shooting with a long focal length, since the long lens will amplify the amplitude of the camera, slight shaking will also cause greater blur, so the impact of hand vibration on the clarity of the picture

Abstract

The invention provides a camera module which comprises a fixed component, a movable component, a fulcrum element, a magnetic driving component and a U-shaped magnetic conducting part, wherein the fixed component is provided with a first containing space; the movable component is arranged in the first containing space; the fulcrum element is arranged between the fixed component and the movable component and is partly contained in the fixed component and partly contained in the movable component. The magnetic driving component can drive the movable component to rotate relative to the fixed component by taking the fulcrum element as a fulcrum, thus compensating the vibration of the camera module. The magnetic driving component is partly arranged in the fixed component and is partly arranged in the movable component. The U-shaped magnetic conducting part is provided with a first magnetic conducting sheet, a second magnetic conducting sheet and a connecting sheet arranged between the first magnetic conducting sheet and the second magnetic conducting sheet; the first magnetic conducting sheet is fixed on the movable component; and the second magnetic conducting sheet is separated from the fixed component so that the magnetic driving component is arranged between the first magnetic conducting sheet and the second magnetic conducting sheet.

Description

technical field [0001] The invention relates to a camera module, in particular to a camera module with an anti-shake function. Background technique [0002] The camera module uses the shutter to control the length of time that the light is projected onto the image sensing element. For example, when the shutter speed is 1 / 2 second, it means that the time for the image sensing element to receive light is 1 / 2 second. If within this 1 / 2 second As the same beam of light moves on the image sensing element due to vibration, the image sensing element will record the movement track of the light, making the photographed blurred. In order to compensate for the light offset caused by shaking, camera modules using image stabilization systems to prevent shaking began to appear in the 1990s. For details, please refer to the paper "Opt integrated circuit al imagestabilization for digital cameras" published by Cardani B. et al. in Control Systems Magazine, IEEE (Volume 26, Issue 2, Page(s):...
