Patent ID: 8902291

Claim:
A 3D image capture device comprising: a light-transmissive section with N light-transmissive areas (where N is an integer that is equal to or greater than three) that have mutually different transmission wavelength ranges; a solid-state image sensor including a photosensitive cell array and a color filter array that is arranged to face the photosensitive cell array, the solid-state image sensor being arranged to receive the light that has been transferred through the light-transmissive section, wherein the photosensitive cell array and the color filter array are both made up of a number of unit elements and wherein each said unit element includes N photosensitive cells and N color filters, each said color filter being arranged to face an associated one of the N photosensitive cells, the color filters having mutually different transmission wavelength ranges; an optical system configured to produce an image on an imaging area of the solid-state image sensor; and a signal processing section configured to process the output signal of the solid-state image sensor, wherein the transmission wavelength ranges of the N light-transmissive areas and the N color filters are defined such that the light that has been transferred through at least one of the N light-transmissive areas is transmissible through at least two of the N color filters, and wherein the signal processing section: generates data representing at least two images with parallax by generating signals representing at least two of the respective intensities of light rays that are incident on the N light-transmissive areas based on the output signals of the N photosensitive cells, and adds a signal representing the intensity of a light ray that has been incident on one of the N light-transmissive areas to a signal representing the intensity of a light ray that has been incident on another one of the transmissive areas, thereby raising the level of the signal representing the intensity of the light ray that has been incident on the latter transmissive area.
