First Claim
1. A computer-readable storage medium having stored therein an overhead map resource generation program which is executed by a computer of an overhead map resource generation apparatus for generating a resource for displaying an overhead map corresponding to a virtual three-dimensional space, the overhead map resource generation program causing the computer to function as:
- shooting means for shooting an overhead image of a region in the virtual three-dimensional space with a virtual camera provided in the virtual three-dimensional space;
determination means for determining whether or not information about a color included in the overhead image shot by the shooting means satisfies a predetermined condition; and
resource data generation means for generating resource data by accumulating, in a predetermined storage medium, image data of the overhead image which the determination means determines does not satisfy the predetermined condition, andprocessing performed by the shooting means, the determination means, and the resource data generation means being repeated until all overhead images corresponding to a predetermined region in the virtual three-dimensional space are shot by the shooting means.

Abstract
In a virtual three-dimensional space, an overhead image of a region in the virtual three-dimensional space is shot by a virtual camera provided in the virtual three-dimensional space. Next, it is determined whether or not the information about a color included in the shot overhead image satisfies a predetermined condition. Image data of the overhead image which it is determined in the result of the determination does not satisfy the predetermined condition is accumulated in a predetermined storage medium, thereby generating resource data. The above processing is repeated until all overhead images corresponding to a predetermined region in the virtual three-dimensional space are shot.
