Abstract

The invention provides a camera module assembling method, which comprises the following steps: disposing a first sub lens and a photosensitive assembly on an optical axis of a second sub lens to forman imageable optical system; increasing an actually measured resolving power of imaging of the optical system by adjusting a relative position of the first sub lens relative to the second sub lens; reducing the inclination of an actually measured image plane, acquired by the photosensitive element, of the imaging of the optical system to a second threshold value by adjusting an included angle of the axial line of the photosensitive assembly relative to the middle axial line of the second sub lens; and connecting the first sub lens, the second sub lens and the photosensitive assembly. The invention further provides a corresponding camera module. The camera module assembling method can increase the resolving power of the camera module; the process capability index of a large batch of produced camera modules can be increased; the entire cost of an optical imaging lens and module can be reduced; the disqualification rate can be reduced; the production cost is reduced; and the imaging quality is improved.

Description

technical field

[0001] The present invention relates to the field of optical technology, and in particular, the present invention relates to a solution for a camera module. Background technique

[0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on.

[0003] In order to meet more and more extensive market demands, high pixel, small size, and large aperture are irreversible development trends of existing camera modules. The market has put forward higher and higher demands on the imaging quality of camera modules. Factors affecting the resolution of a camera module with a given optical design include the quality of the optical imaging lens and manufac...
