Abstract: 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.

Abstract: This image encoding method encodes at least one unit contained in a picture, and includes: a first flag generating step (S221) for generating a first flag indicating whether or not the times that a virtual decoder reads encoded data from a buffer for storing the encoded data are set in units of the units; a second flat generating step (S222) for, when the times are set in units of the units, generating a second flag indicating whether the intervals between the read times of the plurality of units are fixed or arbitrary; and a bitstream generation step (S223) for generating an encoded bitstream containing the encoded data, the first flag, and the second flag.

Abstract: An image encoding method comprises: a deriving step (S1201) of deriving a candidate of a predicted motion vector from an adjacent motion vector; an adding step (S1202) of adding the candidate to a list; a selecting step (S1203) of selecting the predicted motion vector from the list; and an encoding step (S1204) of encoding a current block and encoding a current motion vector. In the deriving step (S1201), when a current reference picture and an adjacent reference picture are each determined to be a long-term reference picture, the candidate is derived by a first deriving method. When the current reference picture and the adjacent reference picture are each determined to be a short-term reference picture, the candidate is derived by a second deriving method.
