| 发明名称 | Deblocking filter and display device having the same | ||
| 摘要 | 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. | ||

| 主权项 | 1. A deblocking filter comprising: a color resolution expansion unit configured to increase a color resolution of input video data to generate first video data; an edge filtering unit configured to perform a blurring operation on a block edge of the first video data based on block size information to generate second video data; and a color resolution contraction unit configured to reduce a color resolution of the second video data to generate output video data, wherein a color resolution of the output video data is the same as a color resolution of the input video data. | ||
