摘要： A multiprojection system that displays one color image by joining a plurality of color images projected by respective projectors is disclosed. The system includes an image capturing section including an optical section having a plurality of filter characteristics corresponding to a plurality of basic colors constituting the color image projected by the projectors, and capturing an image of each of the basic colors via the optical section; and a calculating section calculating offset correction data for each of the basic colors on the basis of a luminance distribution of offset light of each of the basic colors obtained by allowing the image capturing section to capture a black level image projected by the projectors.

摘要： A color reproduction system includes a color image display unit capable of displaying a color image of four or more primary colors, and a color converting unit for converting input three-primary color signals into color image signals of respective primary colors of the color image display unit. The color converting unit includes an area deciding section that decides a color conversion area to which the input three-primary color signals belong in a three-dimensional color space, and a color image signal calculating section that converts the input three-primary color signals into color image signals of respective primary colors based on color conversion parameters corresponding to a color conversion area decided by the area deciding section.
