Camera module group

Abstract

The invention provides a camera module which comprises a lens module used for imaging, an image sensing module connected to the image side of the lens module, and a protecting film covering the outer surface of the lens module. As internal and external threads of a lens barrel and a lens holder are isolated from the environment owing to the protecting film, dust or dregs and so on are prevented from getting into the gaps of the internal and the external threads of the lens barrel and the lens holder during manufacturing and transportation processes. In this way, no dust or dregs and so on are hidden in the camera module assembled in an electronic product, or fall in the sensing area of the image sensing module, thus improving the shooting quality and the stability of the camera module.

Description

technical field [0001] The present invention relates to a camera module, in particular to a camera module with dustproof function. Background technique [0002] At present, mass production is carried out in a modular manner, and electronic products with camera functions are used, such as digital cameras, mobile phones, and camera modules for personal digital assistants. During the manufacturing process and transportation process, there are often problems of dust contamination, resulting in product The photo quality and stability are affected. Therefore, reducing external pollution to the camera module, such as dust, will help improve the photo quality of the camera module. [0003] Generally, a camera module includes a lens module for imaging and an image sensor disposed on the image side of the lens module. The lens module includes a lens barrel for accommodating lenses and a lens seat connected with the lens barrel through threads. Because the lens barrel and the lens ba...

AI Technical Summary

Problems solved by technology

When the lens barrel is rotated to adjust the distance between the lens and the image sensor, the dust hidden between the threads will fall on the sensing area of ​​the image sensor. Due to the high sensitivity of the sensing area of ​​the image sensor, it will Due to the falling of dust, the quality of the captured image is reduced
