1. An image processing method, performed by a processor, wherein the image processing method comprises:
generating an average brightness value of each of a plurality windows in image data;
generating a pixel ratio value according to the image data, wherein the pixel ratio value is a ratio of a first pixel number and a second pixel number, the second pixel number is a quantity of a plurality of pixels, the first pixel number is a quantity of at least one first pixel in the pixels, and a brightness vale of the at least one first pixel is larger than a brightness threshold value;
generating a weight value of the each of the windows according to the pixel ratio value, a first brightness weight, and a second brightness weight;
generating an adjusted brightness value according to the average brightness values of the windows and the weight values of the windows; and
performing an auto exposure process according to the adjusted brightness value to generate final image data,
wherein the final image data is for a display panel to display.
