The OV495 is a companion image processor for OmniVision HDR sensor (e.g., OV2775 and OV10640) to provide a complete system solution with fully processed YUV output. It supports up to three captures combination, global and local tone mapping, as well as distortion and perspective correction, and overlay feature. The OV495 integrates a high performance ISP with improved HDR function and MIPI function to deliver a high throughput data-rate for high quality images. The embedded 32-bit RISC processor provides the flexibility to support various automotive applications. The processed video can be output from single- or dual-DVP, MIPI, or NTSC interface.
