Automotive Image Signal Processor reduces design complexity
Digital image solutions provider Omnivision has introduced a sophisticated companion image processor that supports requirements of next-gen vehicle sensing such as surround view, e-mirror, ADAS and interior camera applications.

It supports multiple color filter array (CFA) patterns and provides the option to output stream for both machine vision and human viewing pipelines independently. Additionally, the imaging pipeline has been upgraded over earlier solutions to provide superior image quality. This includes an improved tone-mapping algorithm.

Omnivision’s new OAX4000 promises developers of next-generation automotive single- and multicamera architectures a maximum of flexibility, resulting in future-proof designs for added functionality as market demands change. The new ASIC is capable of processing data streams from up to four cameras (one at 8MP or four at 3MP).

The OAX4000 is a companion ISP for the company’s HDR sensors, designed to provide a complete multicamera viewing application solution with fully processed YUV output. It is capable of processing up to four camera modules with 140dB HDR, along with what Omnivision claims to be the leading LED flicker mitigation (LFM) performance in the industry. It supports multiple CFA patterns, including Bayer, RCCB, RGB-IR and RYYCy. Additionally, the OAX4000 offers more than 30 % power savings over the previous generation.

Traditionally, electronic control modules required two ISPs. With the OAX4000 only one is needed which reduces design complexity and space and improves overall reliability.

The device complies with ASIL B safety standards. It is available now for sampling and mass production.
