    摘要： An image coding apparatus and an image coding method allow selecting, according to an image in a macroblock to be coded, a most appropriate intra prediction mode for controlling the amount of generated code. The image coding apparatus includes a block feature quantity calculator which calculates, based on pixel values of pixels in the current macroblock in an input image, statistical information of each of the pixel values; and an intra-prediction block size determiner which determines, based on the calculated statistical information, an intra-prediction block size according to a predetermined reference such that a larger intra-prediction block size is more likely to be selected when a degree of change in the pixel value corresponding to a predetermined direction in the current macroblock is smaller. A encoder which performs intra-prediction coding on the current macroblock, in units of the intra-prediction block having the determined size.

    摘要： A moving picture coding apparatus is provided, which controls coding of a following stream, according to virtual buffer occupancy determined by a generated amount of coded data and an amount of coded data transferred to an output destination, when generating the following stream, such that a preceding stream and the following stream, which both have an image stream multiplexed with other information, are reproduced seamlessly. The moving picture coding apparatus generates the preceding stream and the following stream by multiplexing the image stream and the other information to form the preceding stream and the following stream, and determines an initial value of the virtual buffer occupancy for the following stream according to an amount of delay resulting from the multiplexing, and the virtual buffer occupancy at an end of the preceding stream.

    摘要： Video signal coding apparatus includes a quantization unit which quantizes a luminance signal of each of a first picture and a second picture coded after the first picture, and quantizes a chrominance signal of each of the first picture and the second picture. A code amount obtainment unit obtains a luminance code amount and a chrominance code amount of each of the first picture and the second picture; and a rate calculation unit calculates a rate of the chrominance code amount with respect to the luminance code amount for each of the first picture and the second picture. A rate control unit changes a coefficient value of at least one of the first matrix and the second matrix used in quantizing the second picture, before the quantization unit quantizes the second picture, so that the rate for the second picture becomes smaller than the rate for the first picture.
