High dynamic range display using multiple projectors

Recently, high dynamic range (HDR) display has been studied actively. HDR display has a high dynamic range of luminance and high gradation. We propose HDR display with four projectors that can present 1024 RGB gradations with a high dynamic range of luminance by converting four projectors' response functions into a response function of the HDR display. This paper shows HDR displays of an input raw image that is projected directly.
