A first candidate having a first motion vector that has been used to code a first block is derived. A second candidate having a second motion vector and a first reference picture index value that identifies a first reference picture corresponding to the second motion vector is derived. A third candidate having a third motion vector and a second reference picture index value that identifies a second reference picture corresponding to the third motion vector is derived. The second and third motion vectors are first and second zero vectors. The first and second reference picture index values are different. One candidate from a plurality of candidates including the first, second, and third candidates is selected. An index identifying the selected candidate is coded. The selected candidate includes a motion vector and a reference picture index value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image coding method, image coding apparatus, image decoding method, image decoding apparatus, and image coding and decoding apparatus","description":"An image coding method and apparatus for coding a current block are provided.
