<P>PROBLEM TO BE SOLVED: To provide a position calculator, a position calculation program, a game unit, and a game program, capable of calculating the positional relation, even if an imaging device is pointed inclined with respect to an imaging object, when calculating the distance between an input device mounted with the imaging device and the imaging object. <P>SOLUTION: This position calculator calculates the positional relation between the imaging device for imaging first and second imaging objects, and the imaging objects. The position calculator acquires a first size indicating the size of an objective image that indicates the first imaging object in the photographed image by the imaging device, and a second size for indicating the size of an objective image that indicates the second imaging object in the photographed image. The position calculator calculates the positional relation between the imaging device and the imaging objects, based on the first and the second sizes. <P>COPYRIGHT: (C)2008,JPO&INPIT |
