Description

Biometric Camera Module

A biometric camera module, especially a biometric camera module that uses a single image receiver and an image processor to simultaneously realize the functions of face recognition and iris recognition. While realizing the biometric function, it does not sacrifice the function of color influence Group.

In today's information age, the Internet has entered a critical period of transformation and compliance development, innovation in the field of financial technology is also advancing, and new technologies such as artificial intelligence and biometrics are more widely used in the payment field. With the rapid development of mobile payment, information security and smart phone industry, the development prospect of biometric technology in the future is broad. While improving payment security, it also brings another payment besides cash, bank card and mobile payment. This method will become a new outlet for the development of financial technology in the future. How to accurately identify a person's identity and protect information security has become a key social problem that must be solved. Traditional cameras only meet the basic functions of video recording/communication and static image capture, and cannot meet the requirements of traditional identity authentication. Forgery and loss are becoming more and more difficult to meet the needs of society. The most convenient and safe solution at present is undoubtedly biometric technology. It is not only simple and fast, but also uses it to identify the identity, which is safe, reliable and accurate. At the same time, it is easier to integrate with computers and security, monitoring, and management systems to realize automated management. However, the traditional biometric camera has a single function, either face recognition or iris recognition. At present, there is no biometric module that integrates face and iris recognition functions. Therefore, how to improve the lack of conventional knowledge for the primary purpose.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide a high-resolution color image receiver that can realize the functions of face recognition and iris recognition at the same time. Functional biometric camera module.

To achieve the above purpose, the present invention provides a biometric camera module, which includes: a substrate with a first side and a second side, the first side has an IR image sensor, an RGB Image sensor, a light source group, a microphone, the aforementioned units are electrically connected to the substrate, an IR lens holder is provided above the IR image sensor, and an IR lens is fixed on the IR lens holder ; An RGB lens is arranged above the RGB image sensor.

Through the use of a single image receiver and image processor in the biometric recognition camera module of the present invention, face recognition and iris recognition functions are realized at the same time, and cost reduction does not require more than one image receiver and image processor; and it has high-resolution color The image receiver realizes the function of biometric recognition without sacrificing the function of color influence.
