Camera modules are integrated optoelectronic devices that convert optical images into digital signals. As critical components in sensors and transducers systems, they combine image sensors, lenses, and signal processing circuits to enable visual data acquisition in modern electronics. Their miniaturization, high performance, and cost-effectiveness have driven advancements in automation, healthcare, security, and consumer electronics.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| CMOS Image Sensors | Low power consumption, high integration, cost-effective | Smartphones, webcams |
| CCD Sensors | Superior image quality, high light sensitivity | Industrial inspection, astronomy |
| Infrared Cameras | Capture non-visible infrared spectrum | Night vision, thermal monitoring |
| 3D Depth Sensors | Generate spatial depth information | AR/VR, robotics |
| Global Shutter Modules | Eliminate motion distortion | High-speed industrial imaging |
| Low-light Cameras | Enhanced sensitivity in dark environments | Surveillance, autonomous vehicles |
A typical camera module consists of: - Optical Lens System: Focuses light onto the sensor - Image Sensor (CMOS/CCD): Converts photons to electrical signals - Image Signal Processor (ISP): Performs color correction and noise reduction - Interface Circuitry: Supports data transmission (MIPI, USB, etc.) - Mechanical Housing: Protects components and ensures optical alignment Advanced modules may integrate autofocus actuators, IR filters, or AI acceleration cores.
