Flare mitigation via deconvolution using high dynamic range imaging

An electronic device comprising:

• a display panel;
• a camera disposed behind the display panel;
• one or more non-transitory computer-readable storage media including instructions;
• and
• one or more processors coupled to the storage media and the camera, the one or more processors configured to execute the instructions to:
• capture, by the camera disposed behind the display panel of the electronic device, a plurality of images at a plurality of exposures, respectively, wherein one or more captured images of the plurality of images comprise one or more flare artifacts;
• generate a high dynamic range (HDR) image by fusing the plurality of images;
• access a HDR point spread function (PSF) from a memory of the electronic device, the HDR PSF being generated, at an initial camera calibration stage, by fusing a plurality of PSFs captured at the plurality of exposures, respectively;
• and
• generate, using an image deconvolution technique, a reconstructed image with flare artifacts mitigated based on the HDR image and the HDR PSF.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of an electronic device, cause the one or more processors to:

• capture, by a camera disposed behind a display panel of the electronic device, a plurality of images at a plurality of exposures, respectively, wherein one or more captured images of the plurality of images comprise one or more flare artifacts;
• generate a high dynamic range (HDR) image by fusing the plurality of images;
• access a HDR point spread function (PSF) from a memory of the electronic device, the HDR PSF being generated, at an initial camera calibration stage, by fusing a plurality of PSFs captured at the plurality of exposures, respectively;
• and
• generate, using an image deconvolution technique, a reconstructed image with flare artifacts mitigated based on the HDR image and the HDR PSF.
