Low light enhancement has gained increasing importance with the rapid
development of visual creation and editing. However, most existing enhancement
algorithms are designed to homogeneously increase the brightness of images to a
pre-defined extent, limiting the user experience. To address this issue, we
propose Controllable Light Enhancement Diffusion Model, dubbed CLE Diffusion, a
novel diffusion framework to provide users with rich controllability. Built
with a conditional diffusion model, we introduce an illumination embedding to
let users control their desired brightness level. Additionally, we incorporate
the Segment-Anything Model (SAM) to enable user-friendly region
controllability, where users can click on objects to specify the regions they
wish to enhance. Extensive experiments demonstrate that CLE Diffusion achieves
competitive performance regarding quantitative metrics, qualitative results,
and versatile controllability. Project page:

低光增强变得越来越重要；我们提出了一种能够提供丰富可控性的 Controllable Light Enhancement Diffusion Model（CLE Diffusion）扩散框架，利用条件扩散模型和照明嵌入来让用户控制所需的亮度水平，同时结合 Segment-Anything Model（SAM）进行用户友好的区域可控性，以实现出色的性能和多样化的可控性。
