摘要：PROBLEM TO BE SOLVED: To execute a highly accurate position management about a plurality of lenses of an imaging device.SOLUTION: An imaging device 1 is an imaging device that moves a lens in an optical axis direction with an initialization position set as a reference to take a picture of a subject, and the imaging device 1 comprises: a first lens 111; a second lens 112; driving units 111M and 112M; a first position detection sensor 201; a second position detection sensor 202; a third position detection sensor 200; and a control unit 105. The driving units 111M and 112M move the first lens 111 and the second lens 112 in the optical axis direction. The first position detection sensor 201 detects a position of the first lens 111, and the second position detection sensor 202 detects a position of the second lens 112, and the third position detection sensor 200 detects the position of the first lens 111 and the position of the second lens 112. The control unit 105 executes initialization processing of determining initialization positions of the first lens 111 and the second lens 112 on the basis of an output from the third position detection sensor 200.SELECTED DRAWING: Figure 8
