To make it possible to adjust a relative positional relationship between an imaging lens and an image pickup device highly precisely within a short period of time, a position adjusting device includes: an image pickup device rotating and holding section (101) for holding an image pickup device (202) at any one of three or more rotational angles; a relationship information obtaining section (103) for obtaining, for each of respective images captured at the rotational angles, information on a relationship between the corresponding rotational angle and a contrast of the image at a plurality of points or regions in the image; a line approximation section (104) for approximating the relationship with use of an approximation line; and an image pickup device adjusting section (105) for rotating the image pickup device (202) so that the image pickup device (202) is held at a rotational angle corresponding to a position at which a plurality of the approximation lines cross each other. |
