1. An image sensor module, comprising: an image sensor configured to receive an image through a lens; and a lens distortion correction device configured to receive a distorted image from the image sensor, wherein the lens distortion correction device comprises: a distortion correction unit configured to correct the distorted image into an undistorted image; and an image enhancement unit configured to enhance the undistorted image using a high-frequency component of the distorted image, wherein the distortion correction circuit corrects the distorted image applying a bilinear interpolation method controlled according to a degree of distortion determined based on a distance from a center of a image, and wherein a plurality of patches in the distorted image and a plurality of patches in the undistorted image each include a low-frequency component and a high-frequency component.
