DE-BLOCKING FILTER AND AN IMAGE DISPLAY DEVICE INCLUDING THE SAME CAPABLE OF NATURALLY EXPRESSING THE BRIGHTNESS OF IMAGE DATA

摘要

PURPOSE: A de-blocking filter and an image display device including the same are provided to increase the resolution of image data before edge filtering and to perform edge filtering by using image data.;CONSTITUTION: A resolution expanding unit(1000) generates first image data by increasing the resolution of input image data. An edge filtering unit(2000) generates second image data through blurring of a first image data block edge. A resolution contraction unit(3000) reduces second image data resolution into input image data resolution.;COPYRIGHT KIPO 2012
