MULTIPROJECTION SYSTEM AND CORRECTION DATA ACQUIRING METHOD FOR MULTIPROJECTION SYSTEM

摘要

A multiprojection system for displaying one color image formed by connecting color images projected from projectors (12), comprising an imaging unit (14) provided with an optical section having filter characteristics corresponding to basic colors constituting the color images projected from the projectors and adapted for capturing images of the basic colors through the optical section and a calculating unit (15) for calculating offset correction data on the basic data on the basis of the distribution of luminance of the offset light of each basic color determined by capturing black-level images projected from the projectors through the imaging unit.
