PROBLEM TO BE SOLVED: To suppress decrease in displayable colors and to improve effect of color calibration by adjacently arranging display devices which are small in their color display characteristics and deciding a calibration value of the display characteristics of the color. SOLUTION: Plural projector units 3 to 11 are arranged in an array in which a total sum of differences in each display color among the projector units 3 to 11 adjacently arranged becomes minimum. In this case, a total sum of differences (a color difference and a difference in chromaticity) of display colors of four colors at four corners among the adjacent projector units 3 to 11. It is decided whether or not this total sum operation processing is completed with all the array combinations of the projector units 3 to 11. Moreover, an array of the projector units 3 to 11 where the difference in chromaticity becomes minimum is selected and this is decided to be an optimal array. Then, on the basis of this optimal array, rearrangement of the array of the plural projector units 3 to 11 of a multivision system is executed.
