Abstract:
1. An imaging device, comprising: a blade driving unit including a base plate having an opening portion serving as an optical path, a blade member movably supported by the base plate between a receded position displaced from the opening portion and a position facing the opening portion, the blade member including an infrared light cut filter blade that shuts off an infrared light, and an electromagnetic driving source that drives the blade member; a lens optical system arranged on the optical path passing through the opening portion; an imaging element that images an object through the lens optical system; a control unit that drives and controls the blade driving unit and the imaging element and that drives and controls the electromagnetic driving source to move the infrared light cut filter blade to the receded position when using the infrared light; a storage unit that stores information regarding an operator in advance; a comparing unit that compares image information on the operator imaged by the imaging element when using the infrared light with information from the storage unit; and a judgment unit that judges a propriety of the operator based on a comparison result of the comparing unit.
