An exemplary 3D image shooting apparatus comprises: a polarized light source an image capturing section that sequentially captures an image of the object that is being illuminated with each of plane polarized light rays, and an image processor. The image capturing section includes: a lens an image sensor and an incoming light transmitting section which has a transparent area and a plurality of polarization filter areas. The polarization filter areas are arranged outside of the transparent area, generally have a concentric ring shape, and include left and right filter areas so that their polarization transmission axis directions define an angle &alpha (0<&alpha<90 degrees). The image processing section generates a plurality of images from light that has been transmitted through the transparent area and light that has been transmitted through the plurality of polarization filter areas.
