摘要

This paper proposes a method for fusing multi-exposed images that can operate on digital cameras or smartphones. The proposed method consists of an automatic exposure bracketing algorithm that determines which exposures to capture and a newly proposed multi-exposure image fusion algorithm. This fusion algorithm attempts to improve the fusion performance on the basis of the recently proposed no-reference image-quality metrics, noting that the exposure change affects the change in the local luminance details, contrast, and colorfulness of a pixel. Experimental results of various sample image sequences show the superiority of the proposed fusion algorithm in terms of both objective and visual evaluations. By using the proposed method, users can capture high-dynamic range images directly on digital cameras or smartphones, without using offline image-processing software.
