Problems solved by technology

It can be seen from the actual focusing efficiency and production efficiency of the camera module that although the focusing method relied on by the prior art can improve the imaging quality of the camera module, the focusing process takes more time, so that it directly leads to The focusing efficiency and production efficiency of the camera module are low, which does not meet the current market reality that the camera module needs to be produced efficiently

Embodiment Construction

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments, so that anyone skilled in the art can make and use the present invention. The embodiments in the following description are by way of example only and modifications will be apparent to those skilled in the art. The general principles defined in the following description will apply to other embodiments, alternatives, modifications, equivalent implementations and applications without departing from the spirit and scope of the invention.

[0047] Such as figure 1 As shown, the camera module used to capture images (such as images or videos) generally includes two types of fixed-focus camera modules and zoom camera modules, which are determined according to whether the focal length can be adjusted when the camera module is used. Classification, whether it is a fixed-focus camera module or a zoom camera module, it includes a photosensitive chip 10 and an optical ...

Abstract

The invention discloses a camera shooting module focusing method based on chromatic aberration. The focusing method comprises the steps of firstly providing a defocusing amount in each test view field and a monotonic function of imaging quality based on chromatic aberration of a camera shooting module in an optical axis direction, and then shooting and analyzing an image of at least one first test pattern of a standard plate by using the camera shooting module to acquire the chromatic aberration of the camera shooting module in the optical axis direction, and acquiring the defocusing amount of the camera shooting module in each test view field based on the chromatic aberration; subsequently, the needed moving amount of an optical lens of the camera shooting module relative to a light sensitive chip can be judged, and thus focusing of the camera shooting module is completed after the position of the optical lens relative to the light sensitive chip is adjusted.

Description

technical field [0001] The invention relates to a manufacturing process of a camera module, in particular to a camera module focusing method based on color difference in the process of manufacturing the camera module. Background technique [0002] At present, thanks to the rapid development of mobile electronic devices, great breakthroughs have been made in related technologies of camera modules, and in recent years, camera modules have been promoted and applied in various fields such as industry, medical treatment, and life. As the quality of the image (such as image or video) acquired by the camera module becomes more and more stringent, after the camera module is manufactured, how to ensure the image quality of the camera module, and how to Among them, how to improve the production efficiency of the camera module while ensuring the imaging quality of the camera module has become an important issue. [0003] During the manufacturing process of the camera module, especiall...
