Patent number: 7406209Abstract: A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.Type: GrantFiled: October 19, 2007Date of Patent: July 29, 2008Assignee: LG Electronics Inc.Inventors: Hyun Mun Kim, Jong Beom Ra, Sung Deuk Kim, Young Su Lee
