Abstract
A video audio recording system includes a video acquisition unit, an audio acquisition unit, a video recording parameter acquisition unit, and an audio emphasis unit. The video acquisition unit acquires a video signal by recording video of a subject. The audio acquisition unit acquires an audio signal by recording a sound. The video recording parameter acquisition unit acquires first information representing a video recording direction of the video acquisition unit and second information representing a positional relationship between the video acquisition unit and the audio acquisition unit. The audio emphasis unit emphasizes, based on the acquired first and second information, the acquired audio signal of the sound arriving in a predetermined direction.
Claims15
A video audio recording system comprising:
- a video acquisition device configured to acquire a video signal by recording video of a subject;
- an audio acquisition device configured to acquire an audio signal by recording a sound;
- wherein the video acquisition device further includes processing circuitry configured to acquire first information representing a video recording direction of the video acquisition device and second information representing a positional relationship between the video acquisition device and the audio acquisition device;
- and
- the audio acquisition device further includes processing circuitry configured to receive the first and second information from the video acquisition device and to emphasize, based on the acquired first and second information, the acquired audio signal of the sound arriving in a predetermined direction.
