Abstract

본 발명은 디지탈 동영상 부호기의 필드 및 프레임 움직임 추정 선택 방법에 관한 것이다.The present invention relates to a field and frame motion estimation selection method of a digital video encoder.

이러한 본 발명은 필드 및 프레임(field and frame)의 영상 데이타를 선택적으로 움직임 추정하여 데이타 전송 효율을 높이고 화질을 개선하는 것으로, 상기 필드 영상 데이타를 필드 베이스트(field based)움직임 추정 방식에 의해 평균 자승 오차(mean square error, MSE)값을 구하고, 프레임 영상 데이타를 프레임 베이스트(frame based)움직임 추정 방식에 의해 평균 자승 오차값을 구하여 필드 및 프레임 움직임 추정을 선택하는 방법으로써, 보다 개선된 화질을 실현할 수가 있다.The present invention improves data transmission efficiency and improves image quality by selectively motion estimation of field and frame image data, and averages the field image data by a field based motion estimation method. Improved image quality by obtaining a square error (MSE) value and obtaining an average squared error value of frame image data by a frame-based motion estimation method. Can be realized.

Claims (2)

필드 및 프레임(field and frame)의 영상 데이타를 선택적으로 움직임 추정하여 데이타 전송 효율을 높이고 화질을 개선하는 것으로, 상기 필드 영상 데이타를 필드 베이스트(field based)움직임 추정 방식에 의해 평균 자승 오차(mean square error, MSE)값을 구하고, 프레임 영상 데이타를 프레임 베이스트(frame based) 움직임 추정 방식에 의해 평균 자승 오차값을 구하여 다음과 같은 수식에 의거하여 필드 및 프레임 움직임 추정을 선택하는 방법.Selective motion estimation of field and frame image data improves data transmission efficiency and improves image quality. Mean field error of the field image data is calculated by a field-based motion estimation method. square field (MSE) value, a frame-based data estimation method, and an average squared error value. The method of selecting field and frame motion estimation based on the following equation. MSE field+K〈MSE frame이면, 필드 베이스트 예측 모드 선택 (여기서, MSE frame은 프레임 베이스트 움직임 추정을 한 경우의 차영상의 평균 자승 오차값을 나타내며, 또한 K는 오셉(offset)값을 나타낸다.)If MSE field + K <MSE frame, field-based prediction mode selection (where MSE frame represents the mean squared error value of the difference image in case of frame-based motion estimation, and K represents an offset value) .) 제1항에 있어서, 상기 옵셋값 K는 8로 설정함을 특징으로 하는 움직임 추정 선택방법.The method of claim 1, wherein the offset value K is set to eight. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
