Overview

The OV490 is a companion ISP processor for the OV10640 (and similar sensors) to provide a full system solution for display-based applications. The OV490 integrates a high performance ISP with improved HDR functionality for high quality images. Furthermore, the OV490 enables RAW output for machine vision downstream processing in parallel with fully processed YUV for display based applications via MIPI CSI-2 interface. It is designed to process single and dual stream input data. The OV490 is equipped with a 32-bit RISC processor for special applications. The RISC CPU acts as a master controlling the whole chip with the firmware code embedded in ROM or in the program RAM. It can access all sub-modules and run complicated algorithms for flexibility.
