61-2 : A Development of Large-Screen Full HD LCD TV with Frame-Rate- Conversion Technology 문제점 방송 contents 에따라 motion blur 및그개선의시인성에차이가있음 개선안 보통영상의경우에는 motion 이너무느리면 motion blur 가느껴지지않으며, 너무빠르면 camera blur 때문에 blur reduction 효과가크지않음 글자스크롤 (telop) 은 motion blur 및그개선이잘시인되므로, 글자스크롤에대해서만특별히 motion compensation 을수행함
