Patent ID: 8780257

Claim:
An imager device including at least: one imager integrated circuit comprising a matrix of pixels for receiving light rays from a scene, several first, second and third focusing means provided side by side on the matrix of pixels, between the matrix of pixels and an inlet face for the light rays in the imager device, such that each of said focusing means is provided facing a group of at least four said pixels associated with said focusing means and forming a 2×2 matrix, and is capable of focusing part of the light rays to said group of associated pixels, the focusing performed by the first, second and third focusing means being different from one another and equivalent to an arrangement of group of associated pixels at three distances which are different towards the inlet face for the light rays in the imager device, fourth means capable of passing, with respect to each group of pixels, the light rays directed towards said group of pixels and passing through the focusing means associated with said group of pixels, and capable of blocking the light rays directed towards said group of pixels and passing through the other focusing means simultaneously to the passing of the light rays directed to said group of pixels through the focusing means associated with said group of pixels, the fourth means avoiding interferences between the light rays received by each group of pixels.
