Indices are detected from a pattern image including a plurality of indices, and first positions of the detected indices on the captured image are calculated. Using parameters associated with an image capturing apparatus, second positions indicating the positions of the indices on the captured image are calculated. While a parameter of a radial distortion of a lens of the image capturing apparatus is fixed, the parameters other than the parameter of the radial distortion of the lens of the image capturing apparatus are corrected using the differences between the first positions and the second positions. Using the corrected parameters, third positions indicating the positions of the indices on the captured image are calculated. Using the differences between the first positions and the third positions, the parameter of the radial distortion is corrected. |
