Shenzhen Camera Module | The Development Path of Camera Module Manufacturers

The development process of camera modules has seen similar success in the two core businesses of Shenzhen Zhongcai Optoelectronics, namely camera module and fingerprint recognition module. This fully reflects the determination of the group to take root in the smart vision track, build long-term core competitiveness, and gradually demonstrate results. Looking ahead to the future, Haopai Technology will continue to devote itself to four major development directions: first, expanding scale and optimizing marginal costs; Secondly, optimize product structure and increase gross profit margin; The third is to promote automated intelligent manufacturing, reduce employees, and improve efficiency; The fourth is to deepen vertical integration and enhance core competitiveness. Qiudi Technology will continue to adhere to the principle of putting customer experience at the center

Iris recognition camera module

At present, commercial iris recognition camera module systems mostly use two types of user self positioning technologies. One is to use distance sensors to sense the distance of people, and the other is to use audio or indicator lights or buzzers to remind people to approach or stay away from the camera, in order to obtain clear iris images. The second is to use mirrors or LCD displays to visually observe one's position, in order to adjust one's position to the appropriate acquisition area and capture clear images. The image acquisition of the iris recognition camera module first requires aligning the human eye to be recognized with the iris camera, adjusting the position of the human eye to enter the acquisition area, in order to obtain high-quality and clear images

Iris recognition camera module background

One of the characteristics of the recognition technology of the iris recognition camera module is its high precision and high security indicators. This is determined by the complexity and non repeatability of the iris structure. According to experts, 75% of information from two different irises may match, and the probability of two different irises generating the same iris code is one in a thousand. This is several to tens of orders of magnitude more precise than any other biometric technology. The drawbacks of iris recognition technology in the iris recognition camera module are also very obvious. One is to use a camera for shooting, which is susceptible to the influence and interference of surrounding light; The second is to use non-contact data entry, which requires the camera to

Considerations for heat dissipation design in camera module factories

In recent years, with the rapid development of science and technology, due to market demand, the performance of camera sensor modules, camera module pixels, and the power consumption of camera sensors have become increasingly high, making their heat dissipation a challenge. The heat dissipation design of the camera module has a certain impact on the effectiveness of the camera. When the temperature is too high, there will be obvious noise in the dark, and some may even have color distortion such as images turning red; Recently, I encountered two customer feedback issues with the temperature of the camera module: one was USB 200W+500W. Due to its small structure, it was designed as a 4-layer board with components arranged on two sides, and the aging test lasted for half an hour
