The invention of the present application realizes image display that when multiple display screens are being used, properly controls the luminance of one display screen on the basis of the luminance of another display screen. An image display system for displaying images in display areas is provided. The image display system includes a first display area, a second display area, and a luminance determination unit. The luminance determination unit is configured to determine luminance of the second display area on the basis of luminance of the first display area and positional relationships between the first display area, the second display area, and a user and to display the second display area at the determined luminance.

Image display system for displaying images in display areas, method for causing computer to function as image display system for displaying images in display areas, and non-transitory computer readable medium that stores program for causing computer to function as image display system for displaying images in display areas

An image display device, image display system, image display method and computer program which are configured so that not only the gradation characteristic at the luminance over 0.05 (cd/m2) but also the gradation characteristic at the luminance less than 0.05 (cd/m2) satisfies the DICOM. The image display device includes an image display unit; and an image processing unit. The image processing unit is configured to display the image data on the image display unit based on first and second gradation characteristics, a luminance of the first gradation characteristic is 0.05 (cd/m2) or more, a luminance of the second gradation characteristic is less than 0.05 (cd/m2), the first gradation characteristic complies with GSDF (Grayscale Standard Display Function) gradation characteristic of DICOM standard, and the first and second gradation characteristics are defined to satisfy a relationship between a JND value and a corresponding luminance.

Image display device, image display system, image display method, and computer program for providing a low-luminance grayscale standard display function (GSDF) display

A liquid crystal display monitor comprises an LCD panel, a conversion section, an LUT, a monitor communication section, a light source control section, and a light source. The conversion section comprises an LUT. The LUT comprises, for example, an LUT for red, an LUT for green, and an LUT for blue corresponding to the three primary colors of RGB. A PC is connected to the liquid crystal display monitor, while an optical sensor is attached to a display screen of the LCD panel. On the basis of brightness (white brightness and single color brightness) and white chromaticity having been acquired in a state that a white screen is displayed at a plurality of gradations of display input gradation, a conversion table for a plurality of colors (each color of RGB) is calibrated so that display characteristics of a color display unit is calibrated.
