DEBLOCKING FILTERING APPARATUS

摘要

A deblocking filtering apparatus is provided to remove the blocking phenomena caused by the brightness compensation and/or color difference compensation. A deblocking filtering apparatus comprises a boundary filtering strength determining unit and a filtering applying unit. The boundary filtering strength determining unit determines the boundary filtering strength between two blocks which are adjacent to each other. If it is determined that the blocks are not intra-coded(S301), the determining unit whether at least one of the blocks has an orthogonal conversion coefficient(S303). The filtering applying unit applies filtering for the blocks according to the boundary filtering strength outputted from the boundary filtering strength determining unit.
