Abstract: An operation method of an image sensor includes detecting a motion region based on a first image and a second image to obtain a detected motion region, the first image corresponding to a first exposure time and the second image corresponding to a second exposure time, the second exposure time being shorter than the first exposure time, determining a weight for the detected motion region, performing signal pre-processing on the first image to generate a pre-processed image, and outputting a third image based on the pre-processed image and the weight.
