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

Abstract
The present invention provides a camera module assembly method, comprising: preparing a first sub-lens and a second sub-assembly, wherein the second sub-assembly includes a second sub-lens and a photosensitive assembly fixed together; Arranged on the optical axis of the second sub-lens to form an imageable optical system; by adjusting the relative position of the first sub-lens relative to the second sub-lens, the optical The measured resolution of the system imaging is increased to a first threshold, and the measured image plane inclination obtained by the photosensitive element is reduced to a second threshold; and the first sub-lens and the second sub-lens are connected. The invention also provides a corresponding camera module. The invention can improve the resolution of the camera module; can improve the process capability index of the mass-produced camera module; can reduce the overall cost of the optical imaging lens and the module; can reduce the defective rate, reduce the production cost, and improve the imaging quality.
