APPARATUS AND METHOD FOR DEBLOCK FILTERING IN A DIGITAL MOVING PICTURE PROCESSING SYSTEM

摘要

An apparatus deblock filters in a digital moving picture processing system with a macro block having a predetermined number of pixel blocks. An external memory controller reads a current sub-block of a current macro block from entire image data stored in an external memory, and delivers image data of an internal pixel block constituting the current sub-block and an external pixel block to a filter-dedicated memory. The filter-dedicated memory stores the delivered image data. A filtering operator performs horizontal filtering on the current sub-block using the stored image data according to a predetermined order, and performs vertical filtering on the current sub-block according to a predetermined order when the horizontal filtering is completed. The external pixel block includes pixel blocks adjacent to a top and a left side among pixel blocks adjacent to the internal pixel block.
