Claim 1:
2. The method according to claim 1, before correcting the to-be-displayed image based on the target look-up table, further comprising:
acquiring an initial look-up table, wherein the initial look-up table is intended to record corrected pixel values corresponding to the plurality of original pixel values; and
acquiring the target look-up table by updating the corrected pixel values in the initial look-up table;
wherein updating the corrected pixel value corresponding to any original pixel value comprises:
when an absolute value of a difference between a third chroma and a fourth chroma is greater than the chroma difference threshold, adjusting the corrected pixel value at least once until the absolute value of the difference between the third chroma and the fourth chroma as adjusted is less than or equal to the chroma difference threshold; wherein the third chroma is a chroma of a third pixel, a pixel value of the third pixel being acquired by converting the original pixel value, and the fourth chroma is a chroma of a fourth pixel displayed by the display device, a pixel value of the fourth pixel being acquired by converting the corrected pixel value.
