PROBLEM TO BE SOLVED: To adjust relative physical relationship of an imaging lens and an image sensor with high precision in a short time.SOLUTION: A positioning device includes a detecting pattern (101), and a position shift controller (102) which adjusts relative position shift of an imaging lens (201) and an image sensor (202) based on asymmetry of contrast on the basis of the center of positioning image. The detecting pattern (101) is placed so that each is captured on either of a plurality of image height on positioning image and an object distance from each corresponding image height to the imaging lens (201) is different. |
