Gerät und Verfahren zur Bewegtbildkodierung

摘要

The present invention relates to a method and apparatus of digital compression encoding of image such as video signal and controlling the quantizing width when encoding and/or controlling the number of bits generated. <??>The method for compressing and encoding a picture is implemented in a moving picture encoding apparatus comprising a control unit (6) for adjusting the target number of bits depending on the result of dividing the error between the target number of bits corresponding to the target bit rate and the number of generated bits required for encoding image segment groups just before by a number of 2 or more, and controlling the quantizing parameter (q-scale) for encoding the image segment groups depending on the adjusted target number of bits. <IMAGE>
