Provided is an image edge correction apparatus and method. The image edge correction apparatus includes an edge information extraction unit extracting edge information of an input image based on luminance change directivity information of the input image and an edge enhancement unit enhancing an edge of the input image by applying different luminance weights to a pixel of interest included in the input image based on the edge information of the input image. Thus, by appropriately enhancing a contour portion of an image while minimizing noise in a plane portion of the image, the sharpness of the image can be improved. |
