摘要

PROBLEM TO BE SOLVED: To make processing parallel further when applying a deblocking filter.SOLUTION: An image processing device includes: a decoding section configured to decode an image from an encoded stream; a horizontal filtering section configured to apply a deblocking filter to a vertical block boundary within an image to be decoded by the decoding section; a vertical filtering section configured to apply a deblocking filter to a horizontal block boundary within an image to be decoded by the decoding section; and a control section configured to cause the horizontal filtering section to filter in parallel a plurality of vertical block boundaries included in a processing unit containing a plurality of coding units and cause the vertical filtering section to filter in parallel a plurality of horizontal block boundaries included in the processing unit.SELECTED DRAWING: Figure 12
