摘要： A variable length encoder 23 multiplexes hint information into an entire region bitstream, the hint information including motion vector limitation information indicating a maximum range in which a search for a motion vector can be performed, GOP size limitation information indicating a GOP size which is the number of pictures belonging to a GOP, and reference configuration specification information indicating a picture to be referred to at the time of decoding each picture belonging to the GOP. As a result, a bitstream of the entire region which is suitable for efficient generation, with a low operation amount, of a bitstream of a partial region can be generated without causing a reduction in the compression efficiency of the bitstream of the entire region.

摘要： When generating a prediction image of a color difference signal, an intra prediction unit 4 carries out an intra prediction process on a target block to be encoded of a color difference signal by using the same intra prediction parameter as that which the intra prediction unit 4 uses when carrying out an intra prediction process on a target block to be encoded of a luminance signal, or carries out the intra prediction process on the target block to be encoded of the color difference signal by applying an average prediction to the target block to be encoded. A variable length encoding unit 13 variable-length-encodes a flag showing whether the intra prediction unit 4 uses the same intra prediction parameter as that used for the luminance signal.

摘要： When the signal format of a color image is YUV4:2:2, and an intra prediction parameter, which is used for an intra-frame prediction process on the chrominance signals in a prediction block, shows the same prediction mode as an intra prediction mode for the luminance signal in the prediction block, an intra prediction unit 4 converts an index indicating the intra prediction mode for the luminance signal, and performs the intra-frame prediction process on the chrominance signals in an intra prediction mode indicated by the index after conversion.
