Improvement of picture quality in variable play of D-2 VTR : Field conversion System using motion adaptive Signal processing
We have develQpped a 皿 otion − adaptive field conversion syste 皿 for nenstandard speed play of a D − 2 co 皿 posite VTR . It is rea 且ized by e じo 皿 binat 圭 en of a Y /C separation techR 重que and a Line − interpoLation technique which adaptive まy use inter − field signals . And 胛 e have deveEepped a new 皿 ot 呈on detecting nethod too . This method add a ... nter − field 皿 otion detect ・ ion by 玉evel co 阻 parison to a conventioua 且 皿 ethod using temporal − spatial filter . With those technique3 it
