COORDINATE CALCULATING APPARATUS AND COORDINATE CALCULATING PROGRAM

A coordinate calculating apparatus detects a coordinate point (detected coordinate point) of an area satisfying a predetermined condition in a captured image for each area. Next, a vector (assumed vector) indicating a relative positional relationship between two position coordinate points in the captured image is set. The coordinate calculating apparatus determines one of the position coordinate points detected by coordinate detecting means, as one of object position coordinate points, and determines the other object position coordinate point using the one position coordinate point and the vector.
