  Multi-exposure image fusion is a method for producing an image with a wide
dynamic range by fusing multiple images taken under various exposure values. In
this paper, we discuss color distortion included in fused images, and propose a
novel color compensation method for multi-exposure image fusion. In the
proposed method, an inverse camera response function (CRF) is estimated by
using multi-exposure images, and then a high dynamic range (HDR) radiance map
is recovered. The color information of the radiance map is applied to images
fused by conventional multi-exposure imaging to correct the color distortion.
The proposed method can be applied to any existing fusion approaches for
improving the quality of the fused images.
