Claim One:
1. A motion picture recording method which performs coding processing of an input picture through inter prediction to record a motion picture, the method comprising the steps of: performing block-based motion search for the input picture to calculate a motion vector of each block; setting up blocks having a similar motion vector as a similar motion area, the similar motion vector included in the motion vectors calculated in the block-based motion search step; calculating a representative motion vector by use of a motion vector provided by each block included in the similar motion area set up in the similar motion area setup step; selecting either the representative motion vector calculated in the representative motion vector calculation step or the motion vector provided by each block, which is to be used for each block in the similar motion area; and generating encoded data by use of a motion vector selected based on the result of the selection in the selection step and a prediction picture of each block generated using the selected motion vector, for each block in the similar motion area.
