A method for correcting a rolling shutter effect is provided. The method includes: obtaining feature point pairs in images, wherein each of the feature point pairs corresponds to a motion vector; obtaining sampling points between two consecutive images in time; setting a moving velocity and an angular velocity of an image capturing unit at each of the sampling points as variables; obtaining estimating motion vectors according to the variables, a focal length of the image capturing unit, and row locations where the feature point pairs are located; executing an optimization algorithm according to a difference between the motion vectors and the estimating motion vectors, to calculate the moving velocity and the angular velocity corresponding to the variables; varying locations of pixels in an image according to the moving velocity and the angular velocity, to generate a first corrected image. Thereby, the rolling shutter effect in an image is removed.
