    摘要: Input moving pictures are encoded with motion-compensated prediction. Detected first is an mount of codes generated for each encoded picture of the input moving pictures. Detected next is an average quantization scale factor of quantization scale factors used for quantizing the pictures of the input moving pictures when encoded. Also detected is picture characteristics of at least the input moving pictures. Complexity of each picture is calculated in response to the mount of codes generated for each picture, the average quantization scale factor and the picture characteristics. An amount of codes to be allocated to a present picture to be encoded is decided in response to the mount of codes generated for each picture, picture characteristics and the complexity of each picture, for obtaining a quantization scale factor for the present picture.
