Camera module and assembling method thereof

Abstract

The invention provides a camera module assembling method, which comprises the following steps: preparing a first sub lens and a second sub assembly, wherein the second sub assembly comprises a secondsub lens and a photosensitive assembly which are fixed together; disposing the first sub lens on an optical axis of the second sub lens to form an imageable optical system; increasing an actually measured resolving power, acquired through the photosensitive element, of imaging of the optical system by adjusting a relative position of the first sub lens relative to the second sub lens, and reducingthe inclination of an actually measured image plane acquired by the photosensitive element to a second threshold value; and connecting the first sub lens with the second sub lens. 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...

Problems solved by technology

However, this process has a limited ability to compensate

Since a variety of aberrations that affect the resolution come from the capabilities of the optical system itself, when the resolution of the optical imaging lens itself is insufficient, the existing photosensitive module active calibration process is difficult to compensate
