PROBLEM TO BE SOLVED: To provide a lens device that can easily and quickly acquire a wide-angle image and telephoto image, and to provide an imaging device that includes such the lens device.SOLUTION: A lens device according to one embodiment is the lens device that comprises an imaging optical system including a central optical system at a center part and an annular optical system at a peripheral part respectively arranged on the same optical axis, in which one is a wide-angel optical system and other is a telephoto optical system. The wide-angle optical system causes a wide-angle image having the center part omitted to be formed onan image formation plane, and the telephoto optical system causes a telephoto image corresponding to the center part to be formed on the image formation plane. According to the lens device of such the embodiment and an imaging device including the such the lens device, the central optical system and annular optical system which are arranged on the same optical axis allow the wide-angle image and the telephoto image to be quickly and easily acquired, which in turn does not cause a parallax between images.SELECTED DRAWING: Figure 4 |
