It is possible to determine whether or not a specific shape candidate obtained from a captured standard image has a corresponding shape in an actual space. A shape surrounded by straight lines is detected from a standard image as a candidate having a rectangular shape. A target object image obtained by imaging a target object representing the candidate having the rectangular shape at a viewing angle different from the viewing angle of the standard image is generated. The generated target object image is detected from a reference image obtained by imaging the target object at a different viewing angle. If the target object image is detected, the target object represented by the candidate having the rectangular shape is determined to be a rectangle. |
