In order to match precisely the appearance of the recorded video sequence with that of real scenes, the limited dynamic range of a camera, that of a display and human visual characteristics have to be considered. In this paper, we propose a method which can record the high dynamic range video sequence with absolute luminance value of the real scenes, and also describe a new tone mapping method based on spatio-temporal human visual characteristics. Experimental results show that proposed methods reproduce the appearance of real scenes from the recorded video sequence.
