Abstract

This paper proposes an HDR display system using multi-projectors for presentation of HDR contents to multi-users. An HDR image is resolved by luminance and the resolved images are assigned to several projectors. The proposed system projects the HDR contents onto a large screen, and the system can display the HDR contents to multi-users. The proposed system realized to output the broad luminance by emitting the light of multi-projectors onto the same screen. In addition, tonal steps of the proposed system increase so that other projectors cover the tonal steps in the region where the dynamic range is expanded. In this paper, we indicate an effectiveness of the proposed system.
