1. An image display system comprising:
a display having a screen configured to display an image;
a camera configured to capture a user space image of a user space that is forward of the screen;
a memory configured to store (i) screen positioning data indicating a position, orientation, and shape of the screen in a prescribed reference coordinate space, (ii) camera positioning data indicating a position and orientation of the camera in the reference coordinate space, and (iii) three-dimensional data representing a three-dimensional object on the reference coordinate space; and
a processor configured to:
identify a user viewpoint position on the reference coordinate space based on the camera positioning data and the user space image captured by the camera,
generate, based on the user viewpoint position, the screen positioning data, and the three-dimensional data, a display image of the three-dimensional object that is viewable in a virtual space from the user viewpoint position via the screen, and
cause the display image to be displayed on the screen of the display.
