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

A method for causing a computer to function as an image display system for displaying images in display areas, the method comprising:

• a luminance determination step,
• wherein the luminance determination step comprises the computer determining 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 so that an index value of light stimulation felt by the user from the second display area when the user is viewing the first display area, realizes a previously set index value, and displaying the second display area at the determined luminance.

A non-transitory computer readable medium that stores a program for causing a computer to function as an image display system for displaying images in display areas, the program causing the computer to perform:

• a luminance determination step,
• wherein the luminance determination step comprises the computer determining luminance of the second display area on the basis of the luminance of the first display area, and positional relationships between the first display area, the second display area, and a user so that an index value of light stimulation felt by the user from the second display area when the user is viewing the first display area, realizes a previously set index value.
