Three dimensional imaging device and image processing device

An image processor that processes a signal that has been obtained by a 3D image capture device that comprises:

• a light-transmitting plate including n transmitting areas, where n is an integer that is equal to or greater than three, that have mutually different transmission wavelength ranges, each of the different transmission wavelength ranges including a first wavelength range;
• the n transmitting areas include a first transmitting area, a second transmitting area and a third transmitting area;
• the first and second transmitting areas are surrounded by the third transmitting area;
• the first transmitting area is made of a member that transmits a light ray falling within one of the cyan, yellow and magenta wavelength ranges;
• the second transmitting area is made of a member that transmits a light ray falling within another one of the cyan, yellow and magenta wavelength ranges;
• the third transmitting area is made of a transparent member;
• the third transmitting area is larger than the first and second transmitting areas;
• a solid-state image sensor which includes a photosensitive cell array and which is arranged to receive the light rays that have been transmitted through the n transmitting areas of the light-transmitting section, the photosensitive cell array including a plurality of unit blocks, each said unit block including N photosensitive cells including a first photosensitive cell that receives light rays falling within the first wavelength range which have been transmitted through the n transmitting areas and that outputs a photoelectrically converted signal representing the intensity of light rays falling within the first wavelength range received, the n photosensitive cells configured to receive light rays falling within mutually different wavelength ranges and output photoelectrically converted signals representing the respective intensity of light rays received;
• and
• an optical system which produces an image of light rays transmitted through each areas of the light transmitting plate on an imaging area of the solid-state image sensor,
• wherein the image processor:
• generates signals representing the intensity of light rays that have been incident on the respective areas of the light-transmitting plate using a signal which is obtained by multiplying the photoelectrically converted signal supplied from the first photosensitive cell by a first coefficient, which is a real number that is equal to or greater than zero but less than one, the photoelectrically converted signals supplied from the other photosensitive cells, and spectral transmittances of the n transmitting areas;
• and
• generates at least two image data with parallax using the signals representing the intensity of light rays that have been incident on the respective areas.
