Structure of the camera module and the functional description of each component!
Camera Compact Module (CCM) is an important electronic device for image capture. In short, it is a device that converts the optical signal of an object into a digital signal that can be read and stored. It is mainly composed of lens, image sensor, VCM motor/base, IR filter, circuit board and other components.
camera lens
Lens is a device that can collect light to image sensor. Modern lens is generally a lens group composed of several lenses. Lenses are divided into glass (GLASS) and plastic (PLASTIC) according to their materials. For example, 5P lens represents a lens composed of five plastic lenses, and 1G+5P represents a glass plastic hybrid lens composed of one glass lens and five plastic lenses.
image sensor
Image sensor, commonly known as Sensor, is the core component of the camera module, mainly including CMOS image sensor and CCD image sensor. There are hundreds or tens of millions of photodiodes on its surface. The photodiode will produce photoelectric effect after being illuminated, and convert the light signal into electrical signal. Its quality directly affects the performance of CCM.
VCM
VCM, the voice coil motor in electronics, is a kind of motor. Its main principle is to use a permanent magnetic field to change the coil current in the motor to control the position of the shrapnel or mover and drive the lens to move, so as to achieve automatic focusing of the lens.
IR filter
The function of IR filter is to filter the ultraviolet and infrared light that cannot be observed by the human eye, reflect the unwanted light, remove impurities to prevent the influence of color deviation and reduce stray light. Its characteristics also play a crucial role in the final camera imaging effect.
Circuit board
The base plate of the camera module is composed of a printed circuit board (PCB) or a flexible circuit board (FPC/FPCB), which is responsible for connecting the optical components of the camera with the main processor.
Camera modules have been widely used in mobile phones, automobiles, security, finance, medical, industrial, logistics, entertainment, aviation and other fields. In particular, it has been widely used in daily life and work, such as photography, monitoring, access control and payment. With the development of the intelligent industry, the market space of camera modules also shows an exponential growth trend.
