The invention provides a display image processing method and a system, the an displayed by the display is moved, and the pixel value of the pixel of the moved image at the target pixel position is adjusted, so that the pixel residue of the image is eliminated, and the display effect of the moved image is effectively improved. The method comprises the following steps: controlling the display to display a static image; and controlling the pixel of the image to move from the original pixel position to the target pixel position at least through two frames, and adjusting the pixel value of the pixel of the image at the target pixel position.
