Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a new tone mapping operation for HDR images with
biased intensity distribution. In conventional tone mapping operations, when an HDR image has a bias of intensity distribution, an LDR one mapped from the HDR one has also the bias.To overcome this problem, a conventional contrast enhancement method is combined with a tone mapping operation for the tone mapping in the proposed method.The proposed method enables us to generate high quality LDR images, even when HDR images have some biased intensity distribution.We perform a number of experiments under typical tone mapping operations and contrast enhancement methods.The effectiveness of proposed method is evaluated, based on TMQI, which is one of quality assessments, represented by the objective relationship between HDR and LDR images.
