  • Patent number: 8537154
    Abstract: A theater (54) can be divided into a plurality of booths (64) by booth partition walls (68). By moving the booth partition walls (68), the plurality of booths (64) are combined to form a combined theater (66). When the theater (54) is divided in the plurality of booths (64), each booth (64) provides a booth picture in which images of visitors seated in the booth (64) are incorporated as characters. The combined theater (66) provides a combined-theater picture with the use of screens (70) of all the booths (64). Each booth (64) provides a default picture when a fault occurs in the function of generating a booth picture.
