This 3D image capture device includes an image capturing section 100 and a signal processing section 200. The image capturing section 100 includes a light-transmitting section 2 with first, second and third transmitting areas that have mutually different transmission wavelength ranges, a solid-state image sensor 1 that is arranged to receive the light transmitted through the light-transmitting section, and an optical system 3 that produces an image on an imaging area of the solid-state image sensor. The signal processing section 200 includes an image generating section 7 that generates three image signals, representing the quantities of light rays that have been incident on the first, second and third transmitting areas, based on the output signal of the solid-state image sensor 1, and a parallax estimating section 40 that estimates parallax based on the three image signals.
