A voice extracting means 4 extracts the voice information in the frame section of the outline explanation scene detected by the detecting means 2 from the extracted voice information. An AV summary output means 5 synchronously puts together and outputs the summary video recorded by the video summarizing means 3 and the outline explanation voice recorded by the voice extracting means 4.
