Technical Examples

A method of setting an internal parameter or an external parameter of a camera is provided. In this method, there is acquired a picked-up image obtained by picking up a calibration pattern in which black pattern elements and black-and-white pattern elements are arranged on a plane using the camera. Then, a black continuation area and a white continuation area are obtained by quantizing the picked-up image, the black pattern elements and the black-and-white pattern elements in the picked-up image are judged from each other based on the obtained black area and white area, the pattern elements in the picked-up image are associated with the pattern elements in a space based on an arrangement relationship between the judged black pattern elements and black-and-white pattern elements, and the internal parameter or the external parameter is set.
