摘要:
An apparatus for providing an image is provided. The apparatus comprises a sensor (110) comprising a plurality of sensor pixels, wherein each of the sensor pixels of the sensor (110) comprises one or more photosensitive elements, wherein each of the one or more photosensitive elements comprises a photosensitive area, wherein the sensor (110) is configured to provide image data comprising a plurality of first image pixels, and wherein each of the sensor pixels is configured to provide one of the first image pixels of the image data. Moreover, the apparatus comprises an image reconstructor (120; 220) for providing the image, wherein the image comprises a plurality of second image pixels, wherein the image reconstructor (120; 220) is configured to generate the second image pixels of the image depending on the first image pixels of the image data, wherein the number of the first image pixels of the image data is smaller than the number of the second image pixels of the image data, wherein the image reconstructor (120; 220) is configured to generate each of a group of one or more of the second image pixels depending on at least two of the first image pixels. At least one of the sensor pixels of the sensor (110) comprises two or more photosensitive elements being connected such that said one of the first image pixels provided by said sensor pixel depends on each of the two or more photosensitive elements. Or, the photosensitive area of a first one of the photosensitive elements of the sensor pixels of the sensor (110) has a first shape being different from a second shape of the photosensitive area of a second one of the photosensitive elements of the sensor pixels, wherein said first shape is concave.

Brechung an einer geeignet strukturierten Oberfläche (14) bei beispielsweise Anordnung derselben zwischen Bildebene (18) und abbildender Optik wird verwendet, um auf der einen Seite eine gewünschte Aliasfilterung bzw. Ortstiefpassfilterung auf der Bildebene zu realisieren, wobei auf der anderen Seite die Herstellung solcher strukturierten Oberflächen kostengünstig realisierbar ist. Zudem ist die Plattendicke bis auf die Amplitude der Oberflächenstruktur und Aspekte der Stabilität der Platte für ihre Handhabbarkeit unerheblich, so dass die Integration in optische Systeme vereinfacht wird.
