Abstract
A multi-display system includes: a master display device; a first slave display device; an optical measuring instrument to measure luminance and color displayed by a first image display unit of the master display device; and a deterioration factor calculating unit to calculate a deterioration factor on the basis of a first set of measurement parameters, which represent the luminance and the color measured by the optical measuring instrument, and of initial values of the first set of measurement parameters. The master display device performs adjustment on the basis of the first set of measurement parameters. The first slave display device performs adjustment on the basis of a second set of measurement parameters of a second image display unit of the first slave display device, wherein the second set of measurement parameters are calculated from the deterioration factor and from initial values of the second set of measurement parameters.
