What is Camera Modules? 2025-10-21 Core DefinitionA camera module is a complete functional component that converts optical images into electronic signals. It's not just a single lens or chip, but rather a packaged assembly of precision components. It's the core component that enables photo and video recording in devices like smartphones, computers, cars, and security cameras. You can think of it as the heart and eyes of a "mini camera," responsible for all the basic tasks from "seeing" to "generating digital photos/videos." Main Components of a Camera ModuleA typical camera module typically consists of the following key components: Lens Function: Responsible for collecting light, acting as the camera's "eye." Typically composed of multiple lenses (plastic or glass) to correct for aberrations and focus light. Key Parameters: Focal length, aperture (F-number). Image Sensor Function: This is the "heart" and "brain" of the module. It converts the light signals captured by the lens into electrical signals. It is the most critical component in determining image quality (such as resolution, noise, and dynamic range). Types: There are two main types: CCD (charge-coupled device, primarily used in high-end professional applications) and CMOS (complementary metal oxide semiconductor, currently the dominant form in consumer electronics due to its low power consumption, low cost, and high speed). IR filter Function: Typically installed between the lens and the sensor. The wavelength range of light visible to the human eye is 380nm to 780nm, and sensors are also sensitive to infrared light. Failure to filter out infrared light will result in a color cast (usually a reddish tint) in captured images. The IR filter blocks infrared light and allows only visible light to pass, ensuring accurate color reproduction. Voice coil motor Function: Used to drive the lens and achieve focus. By varying the magnitude and direction of the current flowing through the coil, the front-to-back position of the lens is precisely controlled, ensuring a clear focus on the sensor. Types: Open-loop motor, closed-loop motor, memory metal motor, etc., with different types offering varying focusing speeds and accuracy. Substrate and connector Function: Provides physical support and electrical connections for the image sensor and other electronic components. It connects to the device's mainboard via a flexible circuit board or connector, transmitting data, power, and control signals. Base and bracket Function: Precisely secures and packages all of the above components together, ensuring optical alignment and protecting the delicate internal components from dust, shock, and electromagnetic interference. Camera module workflow A simplified imaging process is as follows: Light → Lens (focuses light) → IR filter (filters infrared light) → Image sensor (converts optical signals into electrical signals) → Internal ISP or main chip (processes the electrical signals, such as noise reduction, color correction, and compression) → Final digital image/video Key Technical Indicators of Camera ModulesThe following indicators are generally used to evaluate the quality of a camera module: Sensor size: Usually expressed in inches (e.g., 1/1.7") or diagonal length. As the saying goes, "a bigger sensor means more," a larger sensor generally means better image quality, less noise, and improved bokeh. Pixel size: The physical size of a single pixel, measured in microns (µm). With the same technology, larger pixels capture more light and provide better low-light performance. Focus methods: Common ones include phase detection, contrast, and laser focus, which affect focus speed and accuracy. Optical image stabilization: Compensates for hand shake by moving the lens or sensor, improving image quality and video stability. Applications: Camera modules are ubiquitous, with applications including, but not limited to: Smartphones: The largest market for camera modules, from rear-mounted multi-cameras to front-facing selfie cameras. Automobiles: Used for backup cameras, 360-degree surround view, autonomous driving visual perception systems (ADAS), and dashcams. Security monitoring: webcams, CCTV, etc. Laptops/tablets: Used for video calls. Medical equipment: endoscopes, dental cameras, etc. Industrial inspection: Machine vision for product defect detection, dimensional measurement, barcode recognition, etc. IoT devices: smart doorbells, drones, AR/VR devices, etc. In short, a camera module is a highly integrated photoelectric conversion system. It's more than just a lens or a sensor; it encompasses a complex combination of optics, mechanics, electronics, and software algorithms. Every digital photo and video we see in our daily lives is first captured and converted by this tiny module.
What is Camera Module? A 2025-07-01 Camera Module, also known as Camera Compact Module, abbreviated as CCM, contains four major components: lens, sensor, FPC, and DSP. The important parts to decide a camera is good or bad are: lens, DSP, and sensor.The key technologies of CCM are: optical design technology, aspherical mirror production technology, optical coating technology. Camera Module Components 1 ) Lens Lens is a device that can receive light signals and converge light signals in the sensor CMOS/CCD. lens determines the light harvesting rate of the sensor, its overall effect relative to a convex lens. Optical lens structure is: lens barrel (Barrel), lens group (P / G), lens protection layer (gasket), filter, lens holder (Holder). Camera module lens is divided into plastic lens (PLASTIC) and glass lens (GLASS), the general camera lens consists of several lenses, usually the lens for camera module is: 1P, 2P, 3P, 1G1P, 1G2P, 2G2P, 4G, etc.. The more the number of lenses, the higher the cost; in general, the glass lens will have better imaging effect compared with the plastic lens. However, the glass lens will be more expensive than the plastic lens. 2) IR CUT (infrared Cut  Filter) There are various wavelengths of light in nature, the human eye to identify the wavelength range of light between 320nm-760nm, more than 320nm-760nm light the human eye can not see; and the camera imaging components CCD or CMOS can see most of the wavelengths of light. Due to the involvement of a variety of light, the color restored by the camera and the naked eye in the color deviation. Such as green plants become gray, red pictures become light red, black becomes purple, etc.. At night due to the filtering effect of the bimodal filter, so that the CCD can not take full advantage of all the light, not to produce snow noise phenomenon and its low-light performance is difficult to be satisfactory. To solve this problem, the use of IR-CUT double filter. IR-CUT dual filter is a set of filters built into the camera lens set, when the lens outside the infrared sensor point to detect changes in the intensity of light, the built-in IR-CUT automatic switching filter can be based on the strength of external light and then automatically switch, so that the image to achieve the best results. In other words, the dual filters can automatically switch filters in daytime or nighttime, so that the best imaging effect can be obtained whether in daytime or nighttime. 3) VCM (Voice Coil Motor) Camera Moodule - VCM Full name Voice Coil Montor, electronics inside the voice coil motor, is a kind of motor. Because the principle is similar to the speaker, so called voice coil motor, with high frequency response, high precision characteristics. Its main principle is in a permanent magnetic field, by changing the size of the DC current in the motor coil to control the stretching position of the spring, so as to drive the up and down movement. Camera compact module widely use VCM to realize the autofocus function, and the position of the lens can be adjusted by VCM to present clear images. 4) Image Sensor Image sensor is a semiconductor chip, its surface has millions to tens of millions of photodiodes, photodiodes by the light will generate an electric charge, the light will be converted into electrical signals. Its function is similar to the human eye, so the performance of sensor will directly affect the performance of camera. 5) DSP Digital Signal Processor (DSP) is a microprocessor especially suitable for digital signal processing operations, and its main application is the real-time and rapid implementation of various digital signal processing algorithms. Function: The main purpose is to optimize the digital image signal parameters through a series of complex mathematical algorithms, and to transmit the processed signal to cell phones, computers and other devices via USB and other interfaces.
