Camera Modules

Camera modules are miniature imaging systems that integrate optical lenses, image sensors, and image processing chips. They are widely used in smartphones, security surveillance, automotive electronics (ADAS), medical endoscopes, and other fields.

 

1. Technical Architecture Layers of Camera Modules

1) Optical Layer

Multi-element aspherical lens (7P/8P design)

Liquid lens technology (enabling 0.5ms fast focus)

Filter array (RGB-IR dual-channel solution)

 

2) Sensor Layer

Backside-illuminated CMOS (BSI) accounts for over 90%

Stacked sensor (Sony Exmor RS technology)

Global shutter vs. rolling shutter feature comparison

 

3) Processing Layer

Dedicated ISP chip (such as the OmniVision OV50A)

Triple A algorithm (autofocus/exposure/white balance)

Computational photography fusion (multi-frame noise reduction + HDR)

 

2. Cutting-edge Technological Breakthroughs of Camera Modules

Folded Optical Path Design: The Huawei Pura 70 series uses a periscope module to achieve 10x optical zoom.

Event-driven sensor (Sony IMX636) for high-speed motion capture.

Quantum dot sensor (Samsung ISOCELL HP9) improves low-light performance by 300%.
