Claim Text:
1. A depth estimating image capture device comprising: a light-transmitting section that is made up of a plurality of portions, each including a diffraction region that diffracts incoming light, a transparent region that transmits the incoming light without diffracting the light, and a polarization region arranged so as to overlap at least partially with the diffraction region; 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; 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; and a signal processing section that processes a signal supplied from the image sensor.
