Abstract

The present invention relates to the field of camera technology, in particular to a miniature optical anti-shake camera module. On the voice coil motor, the image sensor module transmits the image acquired by the lens; the autofocus voice coil motor is fixed on the micro memory alloy optical anti-shake actuator, and the control chip is based on the micro memory alloy optical anti shake actuator. The change of the length of the memory alloy wire is used to pull the autofocus voice coil motor to move, realizing the lens shake compensation. The invention simplifies the module structure, reduces the cost, and has low power consumption. By ingeniously arranging the flexible circuit board, the problem of relative movement between the movable board and the fixed board is solved, and multi-line connection can be realized. The process is simple and the structural stability is high, and It will not increase the overall height of the module, and the product structure will be lighter and smaller.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to a miniature optical anti-shake camera module with optical correction function. Background technique [0002] Miniature auto-focus cameras are widely used in mobile phones, cars, unmanned aircraft, security monitoring, smart home and other products. Ordinary miniature auto-focus camera modules are driven by a miniature voice coil motor to move the lens up and down in the direction of the optical axis. When taking pictures, the control chip drives the voice coil motor to move, thereby realizing the auto-focus function. When taking pictures or videos, the lens will not be able to keep absolutely stable due to human shaking or other reasons, resulting in a certain offset. At this time, the focus and light input of the camera will be affected, which will affect the quality of the image captured by the camera. Generally, this kind of lens deflection occurs in the direction perpendicul...
