1. Introduction to camera module Camera module , full name Camera Compact Module, abbreviated as CCM. CCM includes several major parts: lens, voice coil motor (VCM), sensor, flexible circuit board (FPC), image processing chip (DSP). Working principle: The light gathered by the object through the lens is converted into an electrical signal through the CMOS or CCD integrated circuit, and then converted into a digital image signal through the internal image processor (ISP) and output to the digital signal processor (DSP) for processing and conversion into a standard GRB, YUV and other format image signal. The camera module mainly consists of the following parts: Lens: Focuses light onto the image sensor. Voice coil motor (VCM): Completes the camera's autofocus. IR-cut filter: Filters out invisible light to the human eye. Image sensor: Converts light signals into electrical signals. Flexible printed circuit board (FPCB): Connects the camera module to the main processor and transmits data. The following figure shows the structure of several core components of a common mobile phone camera module. 2. Composition 1. Lens The main function of the lens is to converge the light collected from the outside world onto the image sensor. The principle is pinhole imaging. With different lenses, the light is focused onto the photosensitive chip at the bottom of the lens (that is, the sensor) to form Modern lenses are generally composed of several lenses to achieve more complex imaging effects. Lenses are divided into glass and plastic materials. For example, 2G2P means that this set of lenses is composed of two glass lenses and two plastic lenses. Generally, glass lenses have better imaging effects and are more expensive. 2. VCM (Voice Coil Motor) The full name is Voice Coil Motor, which is a type of motor in electronics. Because the principle is similar to that of a speaker, it is called a voice coil motor, which has the characteristics of high frequency response and high precision. Its main principle is to control the stretching position of the spring sheet by changing the DC current of the coil in the motor in a permanent magnetic field, thereby driving the up and down movement. Mobile phone cameras widely use VCM to achieve the autofocus function. The position of the lens can be adjusted through VCM to present a clear image. A coil is placed in a permanent magnetic field. When the coil is energized, a magnetic field will be generated (Ampere's law), which will generate attraction or repulsion with the peripheral permanent magnet, causing the coil to move under force. If the lens is placed on the coil, the coil can be driven to move back and forth by changing the current size, thereby controlling the position of the lens and completing the focusing function. VCM is usually used with VCM Driver IC (VCM driver chip) and AF (Auto Focus) algorithm. First, the image collected by the Sensor is input into the ISP, and the AF algorithm in the ISP calculates the focus steps of the current image and transmits it to the Driver IC through I2C. The Driver IC calculates the current required to move the coil to that position, thereby accurately controlling the behavior of the lens to achieve the effect of autofocus. Of course, this method can also achieve the effect of Optical Image Stabilizer (OIS), and the principle is the same. VCM Performance Indicators The performance of VCM mainly depends on the ratio of current to travel distance. Starting from the starting current, the current rise must be proportional to the travel distance that can be driven. The smaller the required rising current, the higher the accuracy. At the same time, it also depends on the maximum power consumption, maximum power, and size. VCM classification Structurally, they can be divided into three categories: (1) spring-type structure; (2) ball-type structure; (3) friction type structure. Based on their functions, they can be roughly divided into five categories: (1) Open loop motor; (2) Close loop motor; (3) Alternate motor; (4) OIS optical image stabilization motor (divided into translation type, tilt-shift type, memory metal type, etc.); (5) OIS+Close loop six-axis motor. AF principle After entering the auto focus mode, the Driver increases from 0 to the maximum value, causing the lens to move from its original position to the maximum displacement. At this time, the sensor imaging surface automatically takes pictures and saves them in the DSP. The DSP calculates the MTF (Modulation transfer function) value of each picture through these pictures, and then finds the maximum value in this MTF curve. Through the algorithm, it obtains the current size corresponding to this point, and once again instructs the Driver to provide this current to the voice coil, so that the lens is stabilized on this imaging surface, so as to achieve automatic focus. Zoom and focus A: To achieve optical zoom, a zoom motor (ZOOM) is used By moving the lens inside the lens to change the position of the focus, changing the focal length of the lens, and changing the angle of view of the lens, the effect can be magnified or reduced. B: Auto focus using focus motor (AF) By moving the position of the entire lens (rather than the lens inside the lens) at a micro distance, the focal length of the lens is controlled to achieve clear images. This is a common method used in mobile phones. Optical focus and optical zoom are different concepts: Optical zoom is to change the focus position by moving the relative position of the lens inside the lens, changing the length of the lens focal length, and changing the angle of view of the lens, thereby achieving image magnification and reduction; Optical focus actually adjusts the position of the entire lens (rather than the lens inside the lens) to control the image distance, thereby making the image clearest. 3.
