Abstract
A method includes capturing, by a camera disposed behind a display panel of the electronic device, a plurality of images at a plurality of exposures, respectively. One or more captured images include one or more flare artifacts. The method further includes generating a high dynamic range (HDR) image by fusing the captured images. The method further includes accessing a HDR point spread function (PSF) from a memory of the electronic device. The HDR PSF may be generated, at an initial camera calibration stage, by fusing a plurality of PSFs captured at the plurality of exposures, respectively. The method further includes generating, using an image deconvolution technique, a reconstructed image with flare artifacts mitigated based on the HDR image and the HDR PSF.
