OmniVision tackles automotive camera design complexity with new ASIC ISP
OmniVision Technologies, a developer of advanced digital imaging solutions, has unveiled the OAX4000, a new image signal processor (ISP).
The OAX4000 has been designed to provide greater flexibility for next-generation automotive single- and multicamera architectures, enabling OEMs to future-proof their designs for added functionality as market demands change. The device is intended for multiple automotive applications including surround-view systems, e-mirror, interior and autonomous driving cameras.
The high-performance application-specific integrated circuit (ASIC) is capable of processing data streams from up to four cameras at 3MP or one at 8MP. It supports multiple colour filter array (CFA) patterns and provides the option to output stream for both machine vision and human viewing pipelines independently. In addition, the imaging pipeline has been upgraded to provide superior image quality – this includes the next-generation tone-mapping algorithm.
“Our mission is to help automotive OEMs by understanding the problems they need to solve now, as well as in the future,” said Andy Hanvey, director of automotive marketing at OmniVision. “The new OAX4000 ISP offers the design flexibility and compact size to fit into a wide variety of camera architectures, reducing development complexity and cost. Additionally, this high-performance ASIC has the processing capacity for a wide variety of camera use cases.”
The OAX4000 is a companion ISP for the OmniVision HDR sensors and has been 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 the leading LED flicker mitigation (LFM) performance in the industry and high 8MP resolution.
It supports multiple CFA patterns, including Bayer, RCCB, RGB-IR and RYYCy. Additionally, the company claims that the OAX4000 offers more than 30 percent power savings over the previous generation of devices.
