An imaging apparatus includes: an unpolarized light-emitting portion configured to emit light having an unpolarized component； a polarized light-emitting portion configured to emit light having a predetermined polarized component via a first polarization filter； and an imaging element configured to image a subject, which is irradiated with light by one of the unpolarized light-emitting portion and the polarized light-emitting portion, through a second polarization filter, the first polarization filter and the second polarization filter having polarization directions in an orthogonal relationship to each other, the imaging element being further configured to image the subject irradiated with light by the unpolarized light-emitting portion and the subject irradiated with light by the polarized light-emitting portion in a time division manner and output an unpolarized light image and an orthogonal polarized light image that are obtained as a result of imaging.
