Claim 5:
6. The correction method according to claim 1, wherein the at least two second pixel values in the correction interval include at least three second pixel values; and correcting the at least three second pixel values, includes:
correcting a second pixel value in the correction interval to obtain a first second standard pixel value according to the two first standard pixel values;
correcting a second pixel value located between the first second standard pixel value and one of the two first standard pixel values to obtain a second second standard pixel value according to the first second standard pixel value and the one first standard pixel value; and, performing following operations at least once:

determining a position of a second pixel value currently to be corrected;
correcting the second pixel value currently to be corrected to obtain a current second standard pixel value according to the second standard pixel value obtained in a previous correction and one of the two first standard pixel values, in response to determining that the second pixel value currently to be corrected is located between the second standard pixel value obtained in the previous correction and the one first standard pixel value; and
correcting the second pixel value currently to be corrected to obtain the current second standard pixel value according to two adjacent second standard pixel values, in response to determining that the second pixel value currently to be corrected is located between the two adjacent second standard pixel values.
