Overview

The OV490 is a new powerful companion chip that brings improved high dynamic range (HDR) functionality as well as high-quality image and video processing to next-generation advanced driver assistance systems (ADAS). Working in conjunction with other high-performance image sensors, the OV490 enables extremely flexible system partitioning to support a number of advanced automotive features.

OmniVision's OV490 enables simultaneous output of fully processed YUV or RGB for display-based applications and RAW data for machine-vision downstream processing. It also incorporates unique architecture that is capable of processing two video pipelines, resulting in reduced bill-of-materials.

The OV490 contains a well-defined feature set to fulfill Automotive Safety Integrity Level (ASIL) according to ISO 26262. The companion chip fits into a BGA package, and has completed AEC-Q100 Grade-2 qualifications.
