Abstract
An apparatus and a method for compensating image blocking artifacts are capable of eliminating image blocking artifacts occurring in consecutively input image signals, in advance. The apparatus for compensating image blocking artifacts has a video signal comparing unit for comparing gradation values of video signals which are consecutively input at a predetermined time interval, the video signal comparing unit determining if the difference between the gradation values meets a certain condition, as the image blocking artifacts occur in the consecutively input video signals; and an operation processing unit for removing the image blocking artifacts by adding/subtracting the gradation values of the input video signals when it is determined that the image blocking artifacts occur. By eliminating the image blocking artifacts occurring in the consecutively input image signals, the image blocking artifact compensating apparatus can provide a clearer video on the liquid crystal display.
