High-Quality Image and Video Processing for the Next
Generation of Advanced Driver Assistance Systems (ADAS)
OV490 companion ISP product brief
lead free
available in
a lead-free
package
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.
