A technique of accurately computing information on the position of a terminal which acquires a video is provided. A technique of effectively superimposing a video of a view on a video of information on the view is also provided. A video acquiring section (801) acquires a video of a label having a calibration pattern for computing the direction in which the label is imaged and the distance to the label. A calibration computing section (805) computes, from the calibration pattern, the direction in which the label is imaged and the distance to the label. |
