<p><P>PROBLEM TO BE SOLVED: To provide a coordinate calculation device and program for removing the influence of noise. <P>SOLUTION: A coordinate calculation device detects position coordinates(detection coordinates) in a region matched with predetermined conditions in a photographed image for each of the region. When the plurality of position coordinates are detected, the coordinate calculation device sets a reference (previous vectors or estimated vectors) relating to either a direction connecting two position coordinates in the photographed image or the length of a distance between the two position coordinates. The coordinate calculation device selects the combination of the two position coordinates which is the closest to the set reference from among the combination of the two position coordinates among a plurality of position coordinates as two target position coordinates. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
