Abstract
Very large-area multi-projector display systems have wide applications since they provide immersive environments. The brightness of projectors in a system is not identical due to the design and aging of the bulbs, and optical properties of the projectors. Therefore, it is imperative to coordinate the brightness level and characteristics of projectors in the system. This issue has been addressed by many researchers. However, the state of the art solution has considered the characteristic of the projector's brightness only. In this paper, we propose to take into account the dynamic range of the image content. We expand the dynamic range of the input image to utilize the maximum possible brightness of a projector while satisfying the spatial smoothness constraint. The proposed method achieves a seamless multi-display with impressive improvement of the brightness level.
