The image sensor comprises a plurality of photodiodes arranged as a photodiode array. The plurality of photodiodes includes a first set of photodiodes configured as phase detection photodiodes, and a second set of photodiodes configured as polarization detection photodiodes. In some embodiments, a controller is provided. The controller comprises circuitry configured to process signals from a first set of photodiodes of a photodiode array to obtain depth information; process signals from a second set of photodiodes of the photodiode array to obtain polarization information; process the polarization information to obtain an ambiguous set of surface normals; and process the ambiguous set of surface normals using the depth information to obtain a three-dimensional shape image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices and methods for obtaining three-dimensional shape information using polarization and phase detection photodiodes","description":"In some embodiments, an image sensor is provided.
