High-Performance ASIC Image Signal Processor Reduces Automotive Camera Design Complexity

OMNIVISION’s OAX4000 companion image signal processor (ISP) offers design flexibility for next-generation automotive single- and multicamera architectures, enabling OEMs to future-proof their designs for added functionality as market demands change. Traditionally, electronic control modules required two ISPs, however, only one is needed when using the new OAX4000, reducing design complexity and space, and improving overall reliability. In combination with OMNIVISION’s comprehensive sensor portfolio, the OAX4000 provides the ultimate automotive solution.

The OAX4000 is capable of processing up to four camera modules with 140 dB HDR and it offers the leading LED flicker mitigation (LFM) performance in the industry. Additionally, the OAX4000 offers more than 30% power savings over the previous generation ISP.

Ideal for multiple automotive applications including surround-view systems, e-mirror, and autonomous driving cameras, the OAX4000 is a high-performance application-specific integrated circuit (ASIC) capable of processing data streams from up to four cameras at 3MP, or one camera at 8MP. It supports multiple color filter array (CFA) patterns, including Bayer, RCCB, RGB-IR and RYYCy, and provides the option to output stream for both machine vision and human viewing pipelines independently. Additionally, the imaging pipeline has been upgraded to provide superior image quality. This includes the next-generation tone-mapping algorithm.

The OAX4000 complies with ASIL B advanced safety standards.
