Key point 3: how to test the basic function and reliability of the product?


To ensure that the product can be used smoothly after landing, testing is an essential part. As for the camera module, its basic performance test includes analytical force test, screen test, line test, color deviation test and dark angle test, dirt test and bad point test in white board test environment.

Among them, the analytic power refers to the clarity and image detail expression ability that the camera module can achieve. A more intuitive evaluation method is to visually identify the black-and-white line pairs in the image by taking ISO chart test, and the limit line value of the black-and-white line pair can be identified by the human eye. In the same environment, it is also necessary to check whether there are abnormal screen, lines and color deviation. In the white board test environment, the dark angle is usually checked to detect the brightness uniformity of the module, whether there is dirt in the lens, and whether there are bright spots and bad points in the chip.




In all these links, testing is not only to put forward bugs, but also an important step to improve the development and product design. Therefore, the testing work is often highly professional and rigorous to the product effect. If you want to avoid this large number of selection, development, testing cycle, or suggest the demander directly to the hongruan visual open platform industry chain market for direct procurement.




He Shikun, general manager of JSK, concluded: "in recent years, we have developed fairly well in the field of human face. From 2018 to 2020, the annual growth rate has exceeded 50%. By cooperating with hongsoft, we have also made many camera modules with different schemes and costs, mainly to deal with different choices of different customers, so as to facilitate their simple and low-cost use, and at the same time, it also reduces the entry threshold for more customers who want to be in the field of artificial intelligence.
