The imaging device includes an imaging element 40, an imaging optical system 10, a movable mask 30, and a second filter FR. The imaging optical system 10 forms an image of the subject 5 on the image sensor 40 through the first optical path and the second optical path having parallax with respect to the first optical path. The movable mask 30 includes a first filter SL that passes the first wavelength band and a light-shielding portion 34, and is movable with respect to the imaging optical system 10. The second filter FR is provided in the second optical path, and passes a second wavelength band different from the first wavelength band.撮像装置は、撮像素子４０と結像光学系１０と可動マスク３０と第２のフィルタＦＲとを含む。結像光学系１０は、第１の光路と、第１の光路に対して視差を有する第２の光路で撮像素子４０に被写体５を結像させる。可動マスク３０は、第１の波長帯域を通過させる第１のフィルタＳＬと遮光部３４とを有し、結像光学系１０に対して可動である。第２のフィルタＦＲは、第２の光路に設けられ、第１の波長帯域とは異なる第２の波長帯域を通過させる。
