Abstract
An image decoding method includes: obtaining, from a bitstream, a first temporal motion vector prediction flag, which is a temporal motion vector prediction flag indicating whether or not temporal motion vector prediction is to be used, indicating that temporal motion vector prediction is not to be used on a first picture; decoding the first picture without using the temporal motion vector prediction; and decoding a second picture which follows the first picture in decoding order, with referring to a motion vector of a picture preceding the first picture in decoding order being prohibited.
