Claim One:
1. An imager integrated circuit intended to cooperate with an optical system configured to direct light rays from a scene to an inlet face of the imager integrated circuit, said imager integrated circuit being configured to perform a simultaneous stereoscopic capture of N images corresponding to N distinct views of the scene, N being an integer higher than 1, each of the N images corresponding to light rays directed by a portion of the optical system which is different from those directing the light rays corresponding to the N−1 other images, the imager integrated circuit including: N subsets of pixels made on a same substrate, each of the N subsets of pixels being intended to perform the capture of one of the N images associated therewith, means interposed between each of the N subsets of pixels and the inlet face of the imager integrated circuit, and configured to pass the light rays corresponding to the image associated with said subset of pixels and block the other light rays directed from the optical system to said subset of pixels, and wherein said means include: at least two opaque layers superimposed one above the other with a space therebetween, provided between the pixels and the inlet face of the imager integrated circuit, both opaque layers having, passing therethrough, a plurality of holes forming, towards each pixel, at least one pair of superimposed diaphragms, formed by the alignment of the holes in one of the at least two opaque layers being different than the alignment of the holes in another of the at least two opaque layers, configured to pass a part of the light rays corresponding to the image associated with the subset of pixels of which said pixel is part and configured to block other light rays directed from the optical system to said pixel and corresponding to the other images, and wherein the optical system is facing the two opaque layers, wherein means is configured to pass light rays to at least one first subset of pixels from a portion of a right half of the optical system, pass light rays to at least one second subset of pixels from a portion of a left half of the optical system, block light rays to the at least one first subset of pixels from the portion of the left half of the optical system, block light rays to the at least one second subset of pixels from the portion of the right half of the optical system, and pass light rays from a middle point of the optical system to the first and second subsets of pixels, wherein between the opaque layers and the subsets of pixels, light rays that are not blocked by the opaque layers pass only through a dielectric layer disposed between the opaque layers and the subsets of pixels.
