- 격행 주사된 신호를 처리하여 순행 주사된 신호로 바꾸기 위한 격순 변환장치의 동화상 검출방법에 있어서, 보간하고자 하는 필드의 앞 필드 화소 데이타와 뒤 필드 화소 데이타의 차를 제조시 설정된 제1결정계수와 비교하여 동화상을 검출하는 제1과정과, 상기 보간하고자 하는 화소의 위에 해당하는 화소 데이타와 아래에 해당하는 화소 데이타의 상관도에 따라 제2결정계수 값을 셋팅하는 제2과정과, 시간영역으로 보간할 경우의 값과 공간영역으로 보간할 경우의 값의 차를 상기 제2과정에서 결정된 제2결정계수와 비교하여 동화상을 검출하는 제3과정으로 이루어짐을 특징으로 하는 동화상 검출방법.
- 제1항에 있어서, 보간하고자 하는 화소의 위에 해당하는 화소 데이타와 아래에 해당하는 화소 데이타의 차가 설정된 값인 정지계수보다 큰 경우에 정지화상으로 판단하는 제4과정을 더 구비함을 특징으로 하는 동화상 검출방법.
- 제2항에 있어서, 상기 제2결정계수가 상기 정지계수 이상의 일정한 값을 유지하도록 하는 제5과정을 더 구비함을 특징으로 하는 동화상 검출방법.
- 제1항에 있어서, 상기 제2과정은, 상기 보간하고자 하는 화소의 위에 해당하는 화소 데이타와 아래에 해당하는 화소 데이타의 차의 절대치 값을 제2결정계수로 셋팅함을 특징으로 하는 동화상 검출방법.
- 제1항에 있어서, 상기 제2과정은, 상기 보간하고자 하는 화소의 위에 해당하는 화소데이타와 아래에 해당하는 화소 데이타 차의 절대치를 정수배한 값을 제2결정계수로 셋팅함을 특징으로 하는 동화상 검출방법.
- 제1항에 있어서, 상기 제2과정은, 상기 보간하고자 하는 화소의 위에 해당하는 화소 데이타와 아래에 해당하는 화소 데이타 차의 절대치를 값을 제2결정계수로 셋팅함을 특징으로 하는 동화상 검출방법.
- 제3항에 있어서, 상기 제5과정에 있어서, 상기 제2결정계수와 상기 정지계수를 비교하는 비교단계와, 상기 비교단계에서 상기 제2결정계수가 상기 정지계수보다 작다고 판단되면 상기 정지계수를 제2결정계수로 셋팅하는 셋팅단계로 이루어짐을 특징으로 하는 동화상 검출방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
