Abstract: An image processing method includes: detecting repetition numbers of each image frame of an input image frame sequence, wherein the input image frame sequence includes sequentially inputted at least one first image frame and at least one second image frame, and image data of each first image frame is different from image data of each second image frame; determining a first lookup table according to a first repetition numbers of the at least one first image frame, wherein the first lookup table indicates a plurality of sets of compensation calculations; and using a first set of compensation calculations in the sets of compensation calculations to process the at least one first image frame according to a second repetition numbers of the at least one second image frame.
