1. A method comprising, by an electronic device:
capturing, by a camera disposed behind a display panel of the electronic device, an original image through a semi-transparent pixel region of the display panel, wherein the original image is associated with one or more predetermined point spread functions (PSFs) and includes one or more blurring artifacts;
determining an estimated regularization parameter that reduces a complexity of a deblurring filter for deblurring the original image based on the one or more predetermined PSFs and the one or more blurring artifacts;
applying a self-regularizing inverse filter as the deblurring filter to the original image based on the estimated regularization parameter that reduces the complexity of the deblurring filter; and
generating a deblurred image based on the self-regularizing inverse filter, wherein generating the deblurred image comprises reconstructing the original image utilizing the self-regularizing inverse filter to remove the one or more blurring artifacts.
