摘要： A multivision system (1) in which chromaticity sensors (4) for measuring the colorimetries of displays are provided, color conversion coefficients characteristic of the respective displays are calculated by a color conversion coefficient calculation unit (7) provided in a color calibration unit (5) in accordance with the results of the colorimetry measurement by the chromaticity sensors (4) and stored in a color processing unit (8), and the color calibration unit (5) displays representative colors without performing color conversion, determines target colors automatically in accordance with the results of the colorimetry of the respective colors of the respective displays and calculates the color conversion coefficients automatically so that the representative colors of all the displays agree with the target colors.
