  • Multivision system, color calibration method and display
    Patent number: 6340976
    Abstract: A multi-vision system includes chromaticity sensors for performing colorimetry of a plurality of display units. From colorimetry results obtained from the chromaticity sensors, a color conversion coefficient calculation unit inside a color calibration unit calculates the color conversion coefficient that is characteristic of each display unit. Calculated color conversion coefficients are stored in a color processing unit. The color calibration for this multi-vision system displays representing colors without a color conversion, and from colorimetry results of the representing colors for all the display units, a target color is decided automatically. For all display units, the color conversion coefficients are automatically calculated so that the representing colors are able to be displayed as a target color.
