Abstract

The invention aims at providing a mobile phone camera module distortion test method. The method comprises the steps of adjusting parameters of a camera module to the optimum and adjusting a mobile phone to an automatic mode; placing the mobile phone to face a distortion test square standard plate and enabling an optical axis center of the mobile phone camera module to face the center of the distortion test square standard plate; enabling the mobile phone to face the distortion test square standard plate and enabling the optical axis center of the mobile phone camera module to face the center of the distortion test square standard plate; carrying out photographing; and calculating a distortion value through IMATEST software. The method is simple and easy to operate and is fast and effective; the distortion values can be measured for many times; the time is reduced; and the detection guarantee for production of the camera is provided.

Description

technical field [0001] The invention relates to the detection field of mobile phone cameras, in particular to a method for testing the distortion of a mobile phone camera module. Background technique [0002] With the continuous development of science and technology, the function of the camera of the mobile phone is more and more important. There is a camera module in the mobile phone, and the camera module of the mobile phone is assembled from parts. After the camera module is produced, various tests must be carried out on it, and the test can only be delivered if it meets the standard. One of the tests is the distortion test, which is not perfect at present, so it is very necessary to solve this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for testing the distortion of the camera module of a mobile phone, by first adjusting the parameters of the camera module to the best, then adjusting the mob...
