Provided is an image display system that allows many persons to use multiple monitors without feeling color differences between the monitors. An image display system for displaying images on display devices includes multiple display devices, a spectral data acquisition unit, a candidate color matching function acquisition unit, a color difference calculation unit, and a color matching function selection unit. The spectral data acquisition unit is configured to acquire spectral data of the display devices. The candidate color matching function acquisition unit is configured to acquire multiple selection candidate color matching functions that are candidate color matching functions that may be selected by the color matching function selection unit. The color difference calculation unit is configured to calculate color differences between the display devices with respect to each of the selection candidate color matching functions using the spectral data. The color matching function selection unit is configured to select a color matching function that reduces color differences in appearance for many observers, from the selection candidate color matching functions on the basis of the calculated color differences.

The present invention provides a measurement method capable of measuring a physical property value of light output based on a pixel value at any coordinates in an original image. According to the present invention, provided is a measurement method including a display control step of displaying a patch image generated based on a pixel value at target coordinates in the original image, on a display screen at patch display coordinates different from the target coordinates; and a measurement control step of measuring the physical property value of the light from the patch image displayed on the display screen.
