Compact Image Signal Processor for Surround View Automotive Imaging

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 OX03A, OX02A, OV2775, OV10650, and OV10640 automotive image sensors.

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 (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 mm x 7 mm BGA package and contains an advanced set of safety mechanisms to enable ASIL rated camera systems.
