JAGGING DETECTION AND IMPROVEMENT METHOD AND DISPLAY DEVICE USING THE SAME

摘要

The present invention relates to a jagging detection and improvement method and a display device using the same. The method of detecting and improving jagging according to the present invention comprises the steps of: detecting a first partial change which is a position where brightness is rapidly changed by scanning pixels from left to right along an Nth (N is a natural number) line of an input image; Predicting a boundary direction from the detected first specific change; Detecting a second sudden change that is a position where the brightness rapidly changes by scanning left to right along a predicted boundary direction; Scanning sequentially from the right pixel of the pixel detected by the first sudden change in the Nth line to determine whether the brightness within a similar range to the brightness of the pixel detected by the first sudden change is equal to or greater than a predetermined number; And detecting a pixel detected by the first partial change as a jigable area when the luminance within the similar range is more than a predetermined number.
