What is the test standard of camera module in Shenzhen?

In the actual production process, mobile phone cameras need to be tested for various functions, mainly including camera resolution, white balance, dynamic range, color reproduction accuracy, phase brightness uniformity, geometric distortion and so on. The important parameters in camera module testing are bright environment and dark environment testing, such as bright spot test, bad line test and dark current test, which need to be tested in the dark environment of all-black screen. During the testing process, the high-current elastic microneedle module can maintain the stability of the connection and protect the camera module of the mobile phone from interference.
