Abstract: An image processing method includes obtaining a background picture including a first and second pixel, wherein the first pixel has a first intensity value in response to that a first sensing element is operated by a fixed exposure time, and the second pixel has a second intensity value in response to that a second image sensing element is operated by the fixed exposure time; extracting the first and second intensity value from the first and second pixel, respectively; performing a computing operation including computing a first exposure time and a second exposure time; and operating the first image sensing element by the first exposure time and the second image sensing element by the second exposure time after the computing operation.
