摘要：
A local motion vector detection unit 66 obtains a local motion vector LMV for each macro block in a coding target frame image. A region setting unit 64 sets multiple global regions in the frame image. A global motion vector calculation unit 68 calculates a global motion vector GMV which indicates the global motion within each global region. A local motion vector difference coding unit 72 performs coding of the difference ΔLMV which has been obtained by making the difference between each of the local motion vectors LMV within the global region and the global motion vector GMV obtained for each global region. A global motion vector difference coding unit 74 performs coding of the difference ΔGMV which has been obtained by making the difference between each of the global motion vectors GMV obtained for corresponding global region and the reference global motion vector GMVB serving as a reference.
