DEVICE FOR DEBLOCKING FILTER OPERATION AND METHOD FOR DEBLOCKING FILTER OPERATION

摘要

A deblocking filter operation device and deblocking filter operation method for eliminating blocking noise which occurs during decoding of coded image data. Continuous pixel data is inputted into eight operation blocks (101 to 108) in units of two items at the same time. The eight operation blocks (101 to 108) are grouped into sets of two operation blocks so as to parallel perform the filtering operation for blocking noise elimination and to end it continuously and in order. The filtered pixel data is pipeline-outputted from every operation block set and outputed from an output selecting circuit (8).
