Abstract:
An image processing device including processing circuitry that performs horizontal filtering determination processes in parallel across a plurality of vertical block boundaries among a plurality of 8×8 blocks within a locally decoded image. The processing circuitry is configured to apply in parallel a horizontal filter to pixels neighboring the plurality of vertical block boundaries within the locally decoded image to which the horizontal filter is determined to be applied by the horizontal filtering determination processes to generate a first filtered image, perform vertical filtering determination processes in parallel across a plurality of horizontal block boundaries among the plurality of 8×8 blocks within the first filtered image, apply in parallel the vertical filter to the pixels neighboring the horizontal block boundaries within the first filtered image to generate a second filtered image, and encode an image using the second filtered image to generate an encoded stream.
