OV491 companion ISP product brief

Compact Image Signal Processor For

Surround View Automotive Imaging

lead free

available in

a lead-free

package

OmniVision's OV491 is a compact image signal

processor (ISP) companion chip that pairs with

OmniVision's portfolio of automotive RAW image

sensors for automotive imaging applications. The

OV491 is ideally suited to streamline surround view

system architectures with dual sensor input capability,

and is compatible with OmniVision's OV2775, OV10650,

and OV10640 automotive image sensors.

(HDR) video up to 1080p resolution at 60 frames per

second (fps), with dual sensor input processing

capabilities up to 30 fps for compatible sensors.

The OV491 comes in an AEC-Q100 Grade 2-qualified

7 x 7 mm BGA package and contains an advanced set of

safety mechanisms to enable ASIL rated camera

systems.

The OV491's support for dual sensor input enables a

system with only two ISP companion chips to process

four camera inputs, each up to two megapixels in

resolution. The OV491 can process high dynamic range
