摘要 |
An image encoding method comprises an encoding step (S911) of encoding coefficient information, a first flag that indicates whether to quantize one or more blocks using a plurality of quantization matrices, a second flag that indicates whether the plurality of quantization matrices are included in a sequence parameter set, and a third flag that indicates whether the plurality of quantization matrices are included in a picture parameter set, and a quantization step (S912) of quantizing a plurality of coefficients. When one or more blocks are to be quantized using a plurality of default matrices, the first flag indicating that one or more blocks are to be quantized using the plurality of quantization matrices, the second flag indicating that the plurality of quantization matrices are not included in the sequence parameter set, and the third flag indicating that the plurality of quantization matrices are not included in the picture parameter set, are encoded in the encoding step. |
