Abstract: A contact lens (1) provided with a front curve (2) formed by a plurality of annular curved surfaces (F1, F2 .....) for distant vision and a plurality of annular curved surfaces (N1, N2 .....) for near vision, which curved surfaces (F1, F2 .....; N1, N2 .....) are arranged concentrically and alternately, characterized in that the curved surfaces for distant vision in at least the central region of the front curve extend so that the curved surfaces for distant vision farther away from the optical axis have centers of curvature (OF1, OF2 .....) positioned farther away from the optical axis and front curve, these centers of curvature of these curved surfaces being arranged so that rays of light entering these curved surfaces and being parallel to the optical axis are condensed on substantially the same point on the optical axis, the curved surfaces for near vision in at least the central region of the front curve extending so that the curved surfaces for near vision farther away from the optical axis have centers of curvature (ON1, ON2 .....) positioned farther away from the optical axis and closer to the front curve, these centers of curvature of these curved surfaces being arranged so that rays of light entering these curved surfaces and being parallel to the optical axis art condensed on substantially the same point on the optical axis. This invention can provide a contact lens which has a front curve formed by alternately arranging annular and concentric curved surfaces for distant vision and annular and concentric curved surfaces for near vision, and which is free from spherical aberration.

Abstract: The system has a target area information generating section to generate target area information which indicates coordinates of a target area on a sensing surface. A projection control section (130) controls a lens shift section based on intersection between diagonal lines of a calibration image and between lines of the area so that the intersection between the image lines moves to the intersection between the area lines. Independent claims are also included for the following: (a) a projector comprising an image processing system; (b) an information storage medium storing a computer readable program causing a computer to perform an image processing method; and (c) an image processing method.
