Position calculation apparatus, storage medium storing position calculation program, game apparatus, and storage medium storing game program
First Claim
1. A position calculation apparatus for calculating a positional relationship between an image pickup device, which is for taking an image of first and second imaging targets, and at least one of the imaging targets, the position calculation apparatus comprising:
- target image size obtaining means for obtaining a first size, which indicates a size of a target image of the first imaging target in the image taken by the image pickup device, and a second size, which indicates a size of a target image of the second imaging target in the image taken by the image pickup device; and
positional relationship calculation means for, based on the first and second sizes, calculating the positional relationship between the image pickup device and the at least one of the imaging targets.

Abstract
A position calculation apparatus calculates a positional relationship between an image pickup device, which is for taking an image of first and second imaging targets, and at least one of the first and second imaging targets. The position calculation apparatus obtains a first size, which indicates a size of a target image of the first imaging target in the image taken by the image pickup device, and a second size which indicates a size of a target image of the second imaging target in the image taken by the image pickup device. Then, based on the first and second sizes, the position calculation apparatus calculates the positional relationship between the image pickup device and the first and second imaging targets.
