Abstract
본 발명은 화면에 나타나는 구획 효과를 방지하기에 적합한 영상 기기의 동영상 부호화 장치에 관한 것으로, 종래의 움직임 벡터 예측기는 복원 영상을 이용하여 움직임 벡터를 찾기 때문에 복원 영상 자체에 왜곡이 있으므로써, 움직임 판단이 잘못 이루어지므로 움직임 벡터를 올바르게 구하지 못해 결국, 화면에 구획 효과가 나타났으나 본 발명에서는 움직임 벡터 판단기(4)가 움직임 벡터 추정시, 지연된 원래의 영상 신호와 현재의 영상 신호를 비교하여 판단하므로써 더욱 정확한 움직임 벡터를 찾을 수 있으므로 화면의 구획 효과가 줄어들고, 영상의 에지가 분명해 지므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a video encoding apparatus of a video apparatus suitable for preventing a partition effect appearing on a screen. Since a motion vector predictor finds a motion vector using a reconstructed image, the motion image is judged by distortion in the reconstructed image itself. Because of this error, the motion vector cannot be obtained correctly, resulting in a partition effect on the screen. However, in the present invention, when the motion vector determiner 4 estimates the motion vector, it is determined by comparing the delayed original video signal with the current video signal. By doing so, a more accurate motion vector can be found, thereby reducing the partition effect of the screen, and the edge of the image becomes clear, which can improve the above-mentioned shortcomings.
