Abstract:
A video projection system includes: at least first and second local video projection units, and a video signal distributing unit adapted to distribute first and second luminance signals to the first and second local video projection units, respectively. The first local video projection unit projects a first view field along with a first maximum luminance of a first luminance distribution, and the second local video projection unit projects a second view field larger than the first view field along with a second maximum luminance of a second luminance distribution smaller than the first maximum luminance. A luminance resolution of the first luminance distribution is equal to a luminance resolution of the second luminance distribution.
