Abstract
A deblocking filter includes a color resolution expansion unit, an edge filtering unit and a color resolution contraction unit. The color resolution expansion unit increases a color resolution of input video data to generate first video data. The edge filtering unit performs a blurring operation on a block edge of the first video data based on block size information to generate second video data. The color resolution contraction unit reduces a color resolution of the second video data to generate output video data, a color resolution of the output video data being the same as the color resolution of the input video data.
