PROBLEM TO BE SOLVED: To enable a user to easily place a plurality of image display devices in a positional relation to be specified for applications and contents in the case of performing image display by using a plurality of screens. SOLUTION: On the system side, a reference image display device 11 and a moving image display device 12 are in an ideal positional relation when the moving image display device 12 is placed so that an image for positioning to be displayed on the side of the reference image display device 11 and an image for positioning to be displayed on the moving image display device 12 are matched when viewed from a viewpoint P. Consequently, for example, when the image for positioning is considered as a straight line, what straight lines should be displayed on each of the image display devices 11, 12 is decided in order that the image (for example, a straight line 20a) for positioning to be displayed on the reference image display device 11 and the image (for example, a straight line 20b) for positioning to be displayed on the moving image display device 12 can constitute the straight line when the user sees these images.
