The AI-ISP chip helps customers reshape lossless image links with a deep AI-integrated computational photography system to comprehensively improve the image quality, performance and power consumption experience of 4K AI-HDR video. AI computing precision and energy efficiency are unprecedentedly powerful. The AI computing of RAW domain floating points greatly enhances information retention volumes, preserves slight differences in dark light or high-light areas, and restores the real human eye experience to the greatest extent possible; the innovative multi-level storage architecture ensures the performance of high-density storage access and avoids the read and write power consumption of redundant storage access; the deeply optimized computing unit ensures the advantages of floating point computing while greatly improving the energy efficiency ratio, achieving industry-leading power consumption in 4K video AI processing scenarios. A computational photography system that integrates AI can greatly improve ghosts introduced by DOL, while taking advantage of the DOL dynamic range. AI-HDR performs 20-bit Ultra HDR computing in the RAW domain, together with AI processing, presents a high dynamic range across the entire link. The SIP-based encapsulation provides AI-ISP with independent DDR bandwidth without increasing the encapsulation area, with transmission speed as high as 8.5 GB/s, so that the super computing power is not limited by system read and write speeds.
