Abstract
본 발명은 티브이에서 고스트를 제거하는 기술에 관한 것으로, 종래의 고스트제거 방법에 있어서, 첫번째 필드를 판별하고, 그 첫번째 필드로 부터 여덟번째 필드를 필드메모리에 저장시킨 수에만 평균화 알고리즘을 수행하고 8의 배수 필드만을 사용하여 평균화 알고리즘을 수행시키는 분제점을 해결하기 위하여 첫번째 입력되는 필드의 극성에 무관하게 평균화 알고리즘을 수행하고, 4의 배수 필드만으로 평균화 알고리즘을 수행시켜 고스트 제거 속도를 향상시킬 수 있게 한것이다.The present invention relates to a technique for eliminating ghosts in a TV. In the conventional ghost elimination method, a first field is determined, and an averaging algorithm is performed only for the number of eighth fields stored in the field memory from the first field. In order to solve the problem of performing the averaging algorithm using only the multiple fields of, the averaging algorithm is performed irrespective of the polarity of the first input field. It is.
