A rubber cylinder sleeve for an offset printing press includes an inner carrier sleeve that has a circumferential and an axial direction. A coupling capacitance is formed at one of terminals of a pattern wire on a board as an inspection object in a non-contact manner, and an inductance and a lead wire are connected to this capacitance. The image generation method can also comprise transformingdisplaying the virtual viewpoint position of the viewpoint-modified image, according to the amount of change of the movable member of the image sensing unit-disposed object.
