This image capture device includes: a light-transmitting section 1 that is made up of a plurality of portions 1AB, each including diffraction regions 1D1, 1D2 that diffract incoming light, a transparent region 1CLR that transmits the incoming light without diffracting it, and polarization regions 1P1, 1P2 arranged so as to overlap at least partially with the diffraction regions 1D1, 1D2; an image sensor in which a plurality of unit elements are arranged two-dimensionally on an imaging area, wherein each of the unit elements includes a first photosensitive cell, a second photosensitive cell, and a polarization filter arranged so as to face the first photosensitive cell; and an imaging section configured to obtain images produced on the imaging area by the light transmitted through the transparent region and by the light transmitted through the diffraction region.
