Claim 8:
9. The method according to claim 1, wherein correcting the to-be-displayed image based on the target look-up table comprises:
acquiring a converted image based on the to-be-displayed image and an EOTF, wherein pixels in the to-be-displayed image correspond one-to-one to pixels in the converted image, and a pixel value of a pixel in the converted image is determined based on a corresponding pixel and the EOTF;
acquiring a corrected converted image by performing a correction process on the converted image based on the target look-up table; wherein the correction process comprises: when the converted image comprises a coarsely corrected pixel value and the plurality of original pixel values do not comprise the coarsely corrected pixel value, determining, in the target look-up table, adjacent pixel values of the coarsely corrected pixel value in the plurality of original pixel values; acquiring a corrected pixel value of the coarsely corrected pixel value based on corrected pixel values corresponding to the adjacent pixel values in the target look-up table; and correcting the coarsely corrected pixel value to be the corrected pixel value of the coarsely corrected pixel value; and
acquiring a corrected to-be-displayed image based on the corrected converted image and an OETF, wherein pixels in the corrected to-be-displayed image correspond one-to-one to pixels in the corrected converted image, and a pixel value of a pixel in the corrected to-be-displayed image is determined based on a corresponding pixel and the OETF.
