Abstract
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.
