Method, system, and computer readable medium for removing flare in images

A system for removing flare in images, the images taken by an image capturing unit which is disposed under a display of an electronic device, the flare caused by a diffraction effect generated when light passes through internal structures of the display, the system comprising:

• at least one memory configured to store program instructions;
• at least one processor configured to execute the program instructions, which cause the at least one processor to perform steps comprising:
• utilizing the image capturing unit to continuously take an equally-exposed image and under-exposed images with variant exposure settings;
• determining whether the flare is in the equally-exposed image;
• in response to determining that the flare is in the equally-exposed image, aligning image objects of the under-exposed images with respect to the equally-exposed image;
• and. removing the flare in the equally-exposed image by using the aligned under-exposed images, wherein the under-exposed images used to remove the flare in the equally-exposed image are normalized in brightness based on the brightness of the equally-exposed image and the normalized under-exposed images are then denoised.

A non-transitory computer-readable medium, utilized for removing flare in images, the images taken by an image capturing unit which is disposed under a display of an electronic device, the flare caused by a diffraction effect generated when light passes through internal structures of the display, the non-transitory computer-readable medium deployed with program ructions stored thereon, that when executed by at least one processor, cause the at least one processor to perform steps comprising:

• utilizing the image capturing unit to continuously take an equally-exposed image and under-exposed images with variant exposure settings;
• determining whether the flare is in the equally-exposed image;
• in response to determining that the flare is in the equally-exposed age, aligning image objects of the under-exposed images with respect to the equally-exposed image;
• and
• removing the flare in the equally-exposed image by using the aligned under-exposed images, wherein the under-exposed images used to remove the flare in the equally-exposed image are normalized in brightness based on the brightness of the equally-exposed image and the normalized under-exposed images are then denoised.
