Patent ID: 6977674

Claim:
A stereo-image capturing device, comprising: an image-sensing system that is configured to sense a first subject image produced by light beams in a first spectrum, a second subject image produced by light beams in a second spectrum, and a third subject image produced by light beams in a third spectrum; a photographing optical system that produces said first, second, and third subject images in said image-sensing system; and an aperture member that comprises first, second, and third apertures; said first aperture is fitted with a first optical filter which selectively transmits light beams of said first spectrum, said second aperture is fitted with a second optical filter which selectively transmits light beams of said second spectrum, and said third aperture is fitted with a third optical filter which selectively transmits light beams of said third spectrum; wherein a segment between said first and second apertures is parallel to a direction of one of a horizontal line and a vertical line of said image-sensing system and a segment between said second and third apertures is parallel to a direction of a remaining one of the horizontal line and the vertical line of said image-sensing system and wherein parallax images projected through said first, second, and third apertures are simultaneously formed on the image-sensing system.
