Coding method and apparatus with candidate motion vectors

A moving picture coding apparatus that codes a current block of a picture, the moving picture coding apparatus comprising:

• a processor;
• and
• a non-transitory storage,
• the processor performing, using the non-transitory storage, processes including:
• deriving one or more candidates of a first type, each of the candidates having a first motion vector predictor derived from a first motion vector that has been used to code a first block;
• deriving a candidate of a second type, the candidate having a second motion vector predictor, the candidate of the second type being different from the candidates of the first type;
• and
• coding an index corresponding to a candidate having a motion vector predictor,
• wherein the candidate is one of a plurality of candidates which includes the candidates of the first type and the candidate of the second type,
• a total number of the candidates of the first type is less than a predetermined maximum candidate number, and
• the predetermined maximum candidate number is fixed for all blocks in the picture.
