PROBLEM TO BE SOLVED: To almost accurately calculate moving vector information to be added to an encoded composite moving image to be transmitted to each video conference terminal equipment by a simple operation by calculating the moving vector information based on moving vector information obtained at the time of decoding each original moving image, a composite position and a reduction ratio for reduction compositing. SOLUTION: A system control part 22 reads out a moving vector value for four macro blocks(MBs) of a position corresponding to the position of an MB read out from a sound/moving picture multi-plexing part 27 by a moving picture encoding/decoding part 26 from a moving vector table. Moving vector information calculated based on moving vector information obtained at the time of decoding respective original moving images constituting a composite moving image, a composite position and a reduction ratio for reduction compositing is added to each encoded composite moving image. Thereby the moving vector information to be added to the encoded composite moving image can be almost accurately calculated without considering the height of correlation between the moving vector information of respective original moving images and the moving vector information of the composite moving image. |
