A method for reducing smear effects of a dynamic image is for an image sensor. The image sensor converts a shot image picture into image data, and the image data is divided into an effective region, an upper optical black region (UOB), and a lower optical black region (LOB). The method includes capturing two continuous image data to serve as a first frame image and a second frame image; calculating brightness difference values between individual pixels at corresponding pixel positions of the LOB of the first frame image and the UOB of the second frame image; comparing the brightness difference values with a threshold; obtaining positions to be compensated in the UOB of the second frame image, when the UOB of the second frame image requires brightness compensation; and compensating brightness values of pixels in the effective region of the second frame image corresponding to the positions to be compensated.
