Abstract
A buffering delay can be reduced and moving picture encoding in low delay is performed while deterioration of picture quality is minimized. A quantization step of performing quantization of input information based on a value of a quantization parameter and decreasing an amount of information; an entropy encoding step of performing entropy encoding processing with respect to an output of the quantization step, and outputting a code generated as a result of the processing and information of a code amount generated as a result of the processing; and a rate control step of determining a value of a quantization parameter based on a result of the information of a generated code amount are provided, and the rate control step makes, for each section smaller than one picture, the value of a quantization parameter large when bit allocation in the section is expected to exceed a predetermined value, and makes the value of a quantization parameter small when the bit allocation in the section is expected to fall below the predetermined value.
