It is possible to easily set information on the relative positions of the displays.

  In addition, by not storing the display graphic with the same mirror image in the graphic database unit 803, even if there is an object on the mirror surface such as a mirror or glass in the room where the display is installed, the relative position can be accurately set. Can be set.

  Further, even when two or more images are received by the image input unit 806, all the displays can be made one by calculating in a chain manner using the relative positions of the known sub-displays relative to the main display 210. Even when it is difficult to shoot as an image, the relative position of each display can be set.

  The image input unit 806 can also correct the input image based on the model information of the equipment used for shooting and the shooting conditions. Thereby, the precision of the relative position to calculate can be made more accurate, and the effort of installation setting can be reduced by using a super-wide-angle lens.
