Abstract (in Japanese) (See Japanese page) 
(in English) This report proposes a novel tone mapping method focusing on an HDR image with dimidiated luminance and spatial distributions of bright and dark regions.We assume that human visual perception does not feel a sense of discomfort even if a magnitude relationship between luminance values of pixels near the boundary between bright and dark regions is reversed
when these regions are definitely divided according to dimidiated luminance and spatial distributions.Under this assumption, we divide an HDR image into bright and dark regions and apply a different tone mapping function to each region independently.We show resulting images represented by using dynamic range effectively and confirm usefulness of the proposed method through subjective evaluation.
