  • Multiple point spread function based image reconstruction for a camera behind a display
    Patent number: 11721001
    Abstract: A method includes capturing, by a camera disposed behind a display panel of an electronic device, an original image through a semi-transparent pixel region of the display panel, and determining a depth position with respect to at least one object identified within the original image. The method further includes accessing, based on the depth position, a plurality of point spread functions (PSFs) corresponding to a plurality of lateral positions at the depth position, and generating a set of image patches based on the plurality of PSFs. Each image patch of the set of image patches is generated based on a different one of the plurality of PSFs. The method concludes with generating a reconstructed image corresponding to the original image based on the set of image patches.
