Abstract: An image processing method includes acquiring a first image during a first exposure time, and a second image during a second exposure time, wherein the first exposure time is smaller than the second exposure time; acquiring the image region with the luminance greater than a first threshold in the second image as a first over-exposure region; acquiring the image region located at corresponding positions of the first over-exposure region and in the first image as a second over-exposure region; comparing the second over-exposure region and the first over-exposure region, for acquiring a first moving-object region; excluding the first moving-object region from the second over-exposure region, to generate a third over-exposure region; acquiring the image region located at corresponding positions of the third over-exposure region and in the second image as a fourth over-exposure region; and combining the third over-exposure region and the fourth over-exposure region.
