A method includes capturing, by a camera disposed behind a display panel of an electronic device, a plurality of point spread functions (PSFs) through a semi-transparent pixel region of the display panel. Each of the plurality of PSFs is captured at a different exposure time. The method further includes generating an intensity dataset corresponding to the plurality of PSFs, the intensity dataset comprises a plurality of pixel location and a plurality of exposure times associated with the respective pixel locations, calculating a plurality of noise statistics values for the plurality of pixel locations of the intensity dataset, respectively, generating a pixel mask, the pixel mask filters the plurality of pixel locations for pixel locations with respective noise statistics values within a particular threshold, generating one or more high dynamic range (HDR) PSFs utilizing the plurality of PSFs and the pixel mask.

High dynamic range point spread function generation for image reconstruction

A method includes capturing, by a camera disposed behind a display panel of an electronic device, a plurality of point spread functions (PSFs) through a semi-transparent pixel region of the display panel. Each of the plurality of PSFs is captured at a different exposure time. The method further includes determining, for each of the PSFs, pixel intensity data for each of a plurality of pixel locations of the PSF. The pixel intensity data is associated with the exposure time of the respective PSF. The method further includes calculating, for each pixel location, a weighted average pixel intensity value based on the pixel intensity data and the exposure time for the respective pixel location over the plurality of PSFs, and generating a high dynamic range (HDR) PSF utilizing the weighted average pixel intensity values.
