If it is determined that the amount of code of the next picture is likely to exceed the upper limit, the code amount controlling section 142 controls an orthogonal transducing section 114 to replace a transform coefficient of a predetermined frequency component with zero, controls an intra predicting section 125 to restrict intra prediction modes to be applied, and controls a mode determining section 127 to restrict inter prediction modes to be applied. The prevent invention can be applied to an encoding apparatus.

摘要： In a picture information coding device for outputting picture compression information based on an AVC encoding scheme, optimum reference relationships in a GOP structure including hierarchical B pictures can be obtained and random access from an I picture that is not an instantaneous decoding refresh picture can be performed.When multiple-frame prediction is performed, with a memory management control operation command generation unit (13), a reference B picture that exists between a picture and a P picture or I picture is registered as a long-term reference picture using a memory management control operation command to manage a picture in a decoded picture buffer. The reference B picture is placed as the first in a reference picture list using a reference picture list reordering command when a B picture that exists between the P picture or I picture and the reference B picture is processed. The long-term reference picture in the decoded picture buffer is set to be a non-reference picture by setting the maximum value of a long-term frame index to [0] using a memory management control operation command when the P picture or I picture is processed. Random access from the I picture that is not an instantaneous decoding refresh picture is performed.

摘要： A coding device makes a GOP setting to input image data, and applies a coding process to the input image data on a macroblock basis successively by intra and inter prediction to output coded data. The device includes an orthogonal transform section; a quantization section; a coding section; and a rate control section. The rate control section includes an activity detection section; and a prediction residual detection section. The rate control section calculates, in pictures configuring a GOP, a target code amount of any picture that has not yet been subjected to the coding process, another target code amount for a macroblock of any of the pictures relating to the coding process from the target code amount of the picture not yet subjected to the coding process, and the quantization scale of the quantization section in which a generated code amount serves as the target code amount.
