What is the structure of the module？
Camera module, as we know that there are various forms of cameras or external interfaces, but the internal modules are basically composed of lenses, bases, filters, sensors, DSP (including ISP), PCB substrates, etc. As for the external interfaces According to different application scenarios of the product, there are various interface types. The same is true for the DSP part. According to different application scenarios, different usage methods, and different processing requirements, some are directly included in the sensor, and some are directly included in the sensor. An external dedicated chip is required for processing.
Lens is a device that leaks light into an image sensor. Modern lenses are usually a group of multiple lenses. Lens is divided into glass and plastic according to different materials
Image sensor, commonly known as Sensor, is the core component of the camera module. There are mainly two types of CMOS image sensors and CCD image sensors. There are hundreds or tens of millions of photodiodes on the surface. The optical signal is converted into an electrical signal, the quality of which directly affects the performance of the CCM.
The function of the IR filter is to filter out ultraviolet and infrared light that cannot be observed by the human eye, reflect unwanted light, remove impurities to prevent the effect of color cast, and reduce stray light. We have 650NM，850NM，940Nm
The base of the camera module is composed of printed circuit board (PCB) or flexible circuit board (FPC/FPCB), which is responsible for connecting the optical elements of the camera to the main processor.
