Moving picture conversion apparatus

摘要

A moving picture conversion apparatus converts first moving image data encoded in accordance with a first motion compensated prediction method into second moving picture data that has a same format as data encoded in accordance a second motion compensated prediction method. The moving picture conversion apparatus determines whether a relationship between a block in the second motion compensation method and an image used as a reference image with respect to the block confirms with a condition. When the relationship is determined to conform with the condition, the moving picture conversion apparatus performs encoding using a motion vector or vectors of the first moving image data corresponding to the block.
