Abstract
Recently, HDR (High Dynamic Range) display has been active studied. HDR display has high dynamic range of luminance and high gradation. Related studies tried to make a HDR display by using multiple projectors. However, it was difficult to make smooth gradation change on projected planes with the multiple projectors. Therefore, the aim of this study is to propose a HDR display with four projectors that can change gradation smoothly by converting four projector's response functions into a response function of the HDR display.
