Method of converting 4:2:0p/4:2:2p progressive scan data and converter |
摘要 |
A method for converting 4:2:0p serial data containing a first line multiplexing luminance data and color difference data and a second line multiplexing only luminance data in pairs into 4:2:2 interlaced data comprising steps of: demultiplexing 4:2:0p data into luminance data and color difference data at a predetermined horizontal picture element position on a first line; demultiplexing 4:2:0p data into luminance data at the predetermined horizontal picture element position on a second line; obtaining an arithmetic mean value of the demultiplexed luminance data on a first line and the demultiplexed luminance data on a second line; and generating 4:2:2 interlaced data at the predetermined horizontal picture element position by multiplexing the obtained arithmetic mean value as luminance data and the demultiplexed color difference data in pairs.
