A method for correcting interference fringes includes: obtaining correction parameter sets of different photographing distances; obtaining a to-be-corrected image and calculating an average depth value of the to-be-corrected image; selecting a target correction parameter set corresponding to the average depth value from the correction parameter sets of different photographing distances; and correcting first pixel values of to-be-corrected pixels at the different coordinate positions in the to-be-corrected image according to different target correction parameters corresponding to the different coordinate positions in the target correction parameter set, to obtain a corrected image. Each of the correction parameter sets includes different correction parameters corresponding to different coordinate positions. The average depth value includes an average value of depth values corresponding to a plurality of to-be-corrected pixels in the to-be-corrected image.

Interference fringe correction method and under-screen system

A method for correcting interference fringes includes: obtaining interference fringe images with different photographing distances; obtaining a to-be-corrected image including to-be-corrected pixels, and calculating a depth value of each to-be-corrected pixel in the to-be-corrected image; selecting, from the interference fringe images with different photographing distances, an interference fringe image corresponding to the depth value of each to-be-corrected pixel as a target interference fringe image; extracting first pixel values of target coordinate positions in the target interference fringe image; and correcting second pixel values of to-be-corrected pixels according to the first pixel values corresponding to the to-be-corrected pixels to obtain a corrected image.
