Claim One:
1. A method of calibrating an image capture environment based on a captured image obtained by capturing an image of a physical space by an image capturing unit that captures the image of the physical space, the method comprising: an imaging step of capturing an image of the physical space using the image capturing unit; a detecting step of detecting an index serving as a reference for calibration from the captured image of the physical space; a calculating step of calculating a position and orientation of the image capturing unit from the index detected in the detecting step; a presenting step of presenting a virtual three-dimensional object which designates the next target position and orientation of the image capturing unit required to acquire calibration information; and a calibrating step of calibrating one of image capturing unit unique information, geometric information associated with the physical space, and a relationship between the image capturing unit and the physical space using the index detected in the detecting step.
