摘要： An image encoding method includes: determining respective decoding times of a plurality of pictures included in a motion picture such that decoding times of a plurality of lower layer picture which do not belong to a highest layer of a plurality of layers are spaced at regular intervals, and decoding timing for each of the plurality of lower layer pictures is identical between a case where the plurality of encoded pictures included in the motion picture are decoded and a case where only the plurality of lower layer pictures are decoded, encoding each of the plurality of pictures included in the motion picture in accordance with the encoding order according to the determined respective decoding times, and generating an encoded stream including the plurality of encoded pictures and the determined respective decoding times for the plurality of pictures.
