High dynamic range point spread function generation for image reconstruction

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 a camera disposed behind the display panel of the electronic device, a plurality of point spread functions (PSFs) through a semi-transparent pixel region of the display panel, wherein each of the plurality of PSFs is captured at a particular exposure time;
• generate an intensity dataset corresponding to the plurality of PSFs, wherein the intensity dataset comprises a plurality of pixel locations and a plurality of exposure times associated with the pixel locations;
• calculate a plurality of noise statistics values for the plurality of pixel locations of the intensity dataset, respectively;
• generate a pixel mask, wherein the pixel mask filters the plurality of pixel locations for pixel locations with respective noise statistics values within a particular threshold;
• and
• generate one or more high dynamic range (HDR) PSFs utilizing the plurality of PSFs and the pixel mask.
