Claim 12:
13. The image processing method of claim 9, wherein the step of determining the first reference value and the second reference value according to luminance values of the plurality of consecutive pixels, the cumulative luminance value increment and the cumulative luminance value decrement further comprises:
for each pixel of the plurality of consecutive pixels, subtracting the cumulative luminance value decrement corresponding to the pixel from the luminance value of the pixel to obtain an initial first reference value and adding the cumulative luminance value increment corresponding to the pixel to the luminance value of the pixel to obtain an initial second reference value;
determining an adjustment value according to a difference between the luminance values and the initial first reference values of the plurality of consecutive pixels or a difference between the luminance values and the initial second reference values of the plurality of consecutive pixels; and
determining the first reference value according to the initial first reference values of the plurality of consecutive pixels and the adjustment value, and determining the second reference value according to the initial second reference values of the plurality of consecutive pixels and the adjustment value.
