Abstract:
1. A camera system comprising: detection means for detecting fitting errors of a camera by detecting only a displacement quantity in a first direction of an image picked up by the camera, a displacement quantity in a second direction of the image picked up by the camera and a displacement quantity in an optical axis rotating direction of the image picked up by the camera; selection means for selecting a rotation correcting quantity closest to the displacement quantity in the optical axis rotating direction detected by the detection means from a plurality of rotation correction maps prepared in advance; computation means for computing, using linear equations, the correcting quantity in the first direction and the correcting quantity in the second direction respectively on the basis of the displacement quantity in the first direction and the displacement quantity in the second direction detected by the detection means; and correction means for correcting the fitting errors of the camera using the displacement in the first direction, the displacement in the second direction and the displacement in the optical axis rotating direction of the image picked up by the camera on the basis of only (a) the rotation correcting quantity selected by the selection means and (b) the correcting quantity in the first direction and the correcting quantity in the second direction computed by the computation means.
