Claim 6:
7. The correction method according to claim 1, further comprising:
after obtaining a first second standard pixel value, dividing the correction interval into two correction sub-intervals according to the first second standard pixel value and the two first standard pixel values, wherein an end point of each correction sub-interval is the first second standard pixel value, and another end point of the correction sub-interval is one of the two first standard pixel values; and
performing following operations at least once:
updating the correction sub-interval to one correction interval, wherein two end points of the correction sub-interval serve as two first standard pixel values in the updated correction interval;
correcting a current second pixel value located between the two first standard pixel values in the updated correction interval to obtain a current second standard pixel value according to the two first standard pixel values in the updated correction interval; and
obtaining two updated correction sub-intervals according to the two first standard pixel values in the updated correction interval and the current second standard pixel value, wherein an end point of each updated correction sub-interval is the current second standard pixel value, and another end point of the updated correction sub-interval is one of the two first standard pixel values in the updated correction interval.
