Abstract
An edge correction apparatus and a method of performing an effective edge correction of an image signal in horizontal, vertical and diagonal directions include generating a two-dimensional (2D) second differential signal from the image signal, generating first differential signals in the horizontal, vertical and diagonal directions from the image signal, selecting one of the first differential signals, combining the selected one and the 2D second differential signal, and correcting the edge of the image signal using the combined signal. Therefore, it is possible to effectively correct edges of the image signal in the horizontal, vertical and diagonal directions.
