Gerät und Verfahren zur Luminanzschätzung für digitale Videosignale

摘要

The invention relates to a process for coding digital data from a sequence of video images carrying out a coding of the difference in luminance (7) between an image segment to be coded and a corresponding segment of an image predicted from a so-called reference image, characterized in that the prediction is made as a function of a luminance compensation (12) of values of luminance of the reference image. The field is that of the compression of digital video data. <IMAGE>
