Abstract (in Japanese) (See Japanese page) 
(in English) We propose a denoising technique for multiple exposure image integration. When acquiring a dark scene, the detail of a dark area is deteriorated by sensor noise. In addition, the dark area is often enhanced by a tone-mapping. Therefore, we have to removal the noise, for a high dynamic range image acquisition. In our method, we use flash image to significantly reduce the noise of multiple exposure image. In our method, multiple exposure image integration is performed in a wavelet domain, where noise removal is achieved by the wavelet-shrinkage for multiple exposures. Our method works well especially for noise in dark areas. We show the validity of the proposed method by comparing with conventional method.
