General Description
The ALX8B series camera module is a high-performance 8-megapixel camera designed by ALG-TECH. It features Omnivision’s high-performance OX08B40 automotive grade image sensor. It also utilizes GMSL protocol for low-latency and reliable multimedia data transmission. This camera module delivers impressive high dynamic range over 120dB, enabling capture across extreme lighting conditions, from intense sunlight to low-light scenarios, and in the same time maintains extremely low dark noise. This camera module is equipped with multi-element aspherical glass lenses, ensuring clear image even in complex environments. Powered by built-in image signal processor (ISP), the ALX8B module provides advanced real-time image enhancement, including noise reduction and color accuracy. These capabilities, combined with its robust design, make it an ideal front-view camera solution for L2 to L4 autonomous driving systems.
