Description

  The present invention relates to a recording technique such as a camera-integrated DVD recorder (DVD video camera) capable of recording moving images and still images on a recording medium.

  Conventionally, video cameras that record captured image data on a magnetic tape are known.

  In recent years, disk video cameras that record image data on a disk recording medium such as a DVD have appeared instead of magnetic tape.

When a DVD is used as a disk recording medium, there are DVD-Video formats with high playback compatibility with general DVD players as recording formats, and some DVD-VR formats that cannot be played back by some DVD players, but various editing is easy. There are formats and the like, and the user switches between these recording formats for shooting. When recording is performed in the DVD-Video format, finalization processing of the DVD disc is necessary to reproduce the disc with a general DVD player (see, for example, Patent Document 1).
