Components of CMOS Camera Module
Lens: The lens is responsible for converging external light and accurately focusing it onto the image sensor. The common lens structure adopts a combination of multiple lenses. In terms of material, it may use a mixture of glass and plastic or an all-glass design to meet the optical requirements in different scenarios.
CMOS sensor: The main function of a CMOS image sensor is to convert optical signals into electrical signals. High-resolution sensors can capture more details, while large pixel sizes help enhance the light-sensing ability in low-light environments.
Image Signal Processor (ISP) : The ISP is responsible for performing operations such as noise reduction, color correction, automatic exposure, and white balance on the raw data output by the sensor. It also supports advanced functions such as HDR synthesis and multi-frame noise reduction. The ISP can be an independent chip or integrated into the main control SoC.
Filter: A filter is used in a module to filter out excess light. The IR Cut Filter is used to block infrared light, while the CFA covers the surface of the sensor. The performance of these filter elements directly affects the color accuracy and signal-to-noise ratio of the image.
Focusing and anti-shake system: Voice coil motors (VCM) and piezoelectric clicks can achieve the auto-focusing function. The optical image stabilization (OIS) system can enhance the stability of imaging.
