Overview

OmniVision's OV493 is a compact image signal processor (ISP) companion chip that brings best-in-class image quality to 360-degree surround-view and video mirror imaging applications. By processing two video streams simultaneously, the OV493 makes it possible for a system with only two ISP companion chips to process four camera inputs, enabling flexible electronic control unit (ECU) designs for surround-view applications and dramatically reducing overall system cost.

While most ISP companion chips are located on the camera module, the OV493 can be placed on the ECU module for unprecedented flexibility and streamlined system architectures. The OV493 is designed to work seamlessly with OmniVision's high-performance OV9716 and OV10640 automotive image sensors, supporting dual sensor input of up to 1.4 megapixels at 30 frames per second (fps) with high dynamic range (HDR) each.

The OV493 comes in an AEC-Q100 Grade 2-qualified 7 x 7 mm ball grid array (BGA) package.
