DarkDiff: Advancing Low-Light Raw Enhancement by Retasking Diffusion Models for Camera ISP

Summary

The article presents DarkDiff, a novel framework that enhances low-light raw images by leveraging pre-trained generative diffusion models in the context of camera image signal processing (ISP). Traditional ISP algorithms often fall short in low-light conditions, leading to oversmoothing and loss of detail. DarkDiff addresses these limitations by retasking diffusion models, resulting in significant improvements in perceptual quality across various benchmarks. The research highlights the potential of combining generative models with conventional image processing techniques to achieve superior outcomes in challenging photographic scenarios.
