PROBLEM TO BE SOLVED: To provide a method of easily calculating coupling precision expected when different scenes are pasted on each other.SOLUTION: Representative positions for each marker which appear in common in images included in an image setΦof scenes captured consecutively in the past and an image setΦof scenes currently captured consecutively are found as scene information. A spread index of a point group is found for representative positions for each marker. Expected coupling precision is calculated based upon the spread index, and the result is displayed in real time to the user who is image-capturing. An eigenvalue of positions for each marker may be used as the spread index of the point group. The expected coupling precision is set according to, for example, a threshold determination result of the spread index of the point group. The user who is image-capturing can confirm, in real time, whether an image included in the scene being currently captured can be coupled to an image included in a scene captured in the past and the expected coupling precision thereof, so that image-capturing with good coupling precision is facilitated. |
