Lens: It is composed of a refraction layer and a filter. The refraction layer has a multi-layer structure, which is mixed with glass or plastic or glass-plastic. The refraction layer completes multiple refractions of light and then projects it to the photosensitive chip. The filter is used to filter out some light that can be observed by the naked eye and can affect the color effect band.
Photosensitive chip: It mainly collects the light folded by the lens and concentrates the light. At present, there are two kinds of packages: plastic and ceramic. The photosensitive area is divided into different sizes. The larger the photosensitive area, the lighter collected, and the unit pixel The higher it is, the better the result will be.
Integrated Circuit Board: An essential part of all electronic devices. The structure is complex and consists of a variety of electronic material components and main control processing chips (DSP). The electronic components mainly play the roles of controlling voltage, reducing power consumption, and filtering interference impurities. The main control processing chip plays a huge role, similar to the CPU of a computer. It mainly compresses and organizes the color data transmitted by the chip and optimizes the effect. Therefore, the computing power of the main control chip plays an important role in the image quality effect presented by the camera module.
The basic components of the camera module are composed of the above three parts, other required structural components are superimposed according to the functions and effects that an imaging device needs to achieve such as adding light panels to enhance the night vision effects, IR-CUT in order to apply to complex environmental changes etc.
