PROBLEM TO BE SOLVED: To provide an imaging device equipped with a simple mechanism to correct focal deviation caused by chromatic aberration. SOLUTION: The imaging device holds an infrared cut filter 6A and a visible light cut filter 6B, and is equipped with a slider 5 which can select either the infrared cut filter 6A or the visible light cut filter 6B as a optical filter to be inserted to the middle of an optical axis connecting imaging lens 1 and an image pickup device 7, and a lens holder 2 which is movable in an optical axis direction while holding the imaging lens. The lens holder 2 is moved in accordance with the change of the optical filter inserted into the optical axis by driving the slider 5. Therefore, an optical path length between the imaging lens 1 and the image pickup device 7 can be changed. COPYRIGHT: (C)2006,JPO&NCIPI
