Abstract: The present invention discloses a method and an apparatus for correcting lens distortion. In some feasible implementation manners of the present invention, image data acquired from a lens is corrected in a horizontal direction; the image data corrected in the horizontal direction is written into a dynamic memory; image data in the dynamic memory is corrected in a vertical direction; and lens distortion correction is performed in two steps: in the horizontal direction and in the vertical direction, so that lens distortion correction is implemented at a low cost. The present invention further discloses a corresponding apparatus for correcting lens distortion.
