Lucky High Dynamic Range Smartphone Imaging

ArXi:2604.19976v1 Announce Type: new While the human eye can perceive an impressive twenty stops of dynamic range, smartcamera sensors remain limited to about twelve stops despite decades of research. A variety of high dynamic range (HDR) image capture and processing techniques have been proposed, and, in practice, they can extend the dynamic range by 3-5 stops for handheld photography. This paper proposes an approach that robustly captures dynamic range using a handheld smartcamera and lightweight networks suitable for running on mobile devices.
