Verfahren und Vorrichtung zur Videocodierung mit hoher Effizienz

摘要

High efficiency coding method and apparatus of a video data, in which even from video data in a fade-in or fade-out state, coded video data which does not cause a deterioration of a picture quality upon decoding of said video data can be obtained. When the image based on the video data is in the fade-in or fade-out state and many outline components are included in the image, a motion vector is detected from the luminance adjusted video data obtained by adjusting the luminance of the video data. When the number of outline components included in the image is small, the motion vector is directly detected from the video data and the video data is encoded by a motion compensation prediction according to the motion vector.
