摘要：
图像编码方法包括以下步骤：导出步骤(S1201)，从相邻运动矢量导出预测运动矢量的候选；追加步骤(S1202)，将候选追加到列表中；选择步骤(S1203)，从列表选择预测运动矢量；以及编码步骤(S1204)，对当前块进行编码，对当前运动矢量进行编码；在导出步骤(S1201)中，在判定为当前参照图片及相邻参照图片分别是长期参照图片的情况下，通过第1导出方式导出候选，在判定为当前参照图片及相邻参照图片分别是短期参照图片的情况下，通过第2导出方式导出候选。
摘要（英）：

An image coding method includes: deriving a candidate for a motion vector predictor from a neighboring motion vector (S1201); adding the candidate to a list (S1202); selecting a motion vector predictor from the list; coding a current block (S1203); and coding a current motion vector (S1204). In the deriving (S1201), the candidate is derived according to a first derivation scheme when each of a current reference picture and a neighboring reference picture is determined to be a long-term reference picture, and the candidate is derived according to a second derivation scheme when each of a current reference picture and a neighboring reference picture is determined to be a short-term reference picture.
