PROBLEM TO BE SOLVED: To accurately adjust the relative position of a photographing lens and an imaging device without using a sophisticated adjusting tool. SOLUTION: A light receiving sensor S1-S4 such as a photo diode is provided on the peripheral part of the effective pixel area 31 of the imaging device 21. Each sensor S1-S4 is arranged at a position separated by equal distance from the center O of the effective pixel area 31. A light source, the photographing lens, and the imaging device are sequentially arranged and the light from the light source enters the photographing lens. Each light receiving sensor S1-S4 receives the light passing the photographing lens. An output signal from each light receiving sensor is outputted to a monitor, and the output levels are compared. Since each light receiving sensor is in the equal distance from the center O, the output level of each light receiving sensor S1-S4 is equal when an optical axis A is aligned with the center O.
