WIPO Patent Application WO/2023/013149
Kind Code:
A1
Abstract:
[Problem] To provide a solid-state image capturing device having a metasurface structure capable of condensing light onto the center of a pixel even if the light is incident on a pixel region from an oblique direction. [Solution] A solid-state image capturing device according to an embodiment of the present invention is provided with a pixel region including a plurality of pixels, and a polarization control element which is provided above a surface of incidence of incident light in the pixel region, and which includes a plurality of microstructures arranged two-dimensionally substantially parallel to the surface of incidence, wherein a position, within a first pixel in the pixel region, of a first microstructure having a maximum length in a first polarization direction of the incident light, among the plurality of microstructures corresponding to the first pixel, depends on a distance from the center of the pixel region to the first pixel.
