Abstract: A sound and video processing system includes: a display, having a rectangular display region, that displays a video image in a circular video-image display region smaller than the rectangular display region; and a sound collector that collects sound. A processor generates emphasized audio data, in which sound is emphasized in at least one direction from a position of the sound collector toward at least one position corresponding to at least one designated location in the video image. In response to receiving designation outside the video-image display region, the processor displays a state display area or an adjustment operation area for the sound to be output from the speaker in a rectangular region which has a diagonal line extending from one of four corners of the rectangular display region to a center of the video-image display region and intersecting with a boundary line of the video-image display region.

Abstract: Sound collection directionality is formed toward a location corresponding to a position designated in a video of a predetermined region which is imaged by a camera apparatus with a microphone array apparatus as a reference, and audio data is collected with high accuracy. In a directionality control system (10), a signal processing unit (33) derives a sound collection direction (θMAh,θMAv) which is directed from an installation position of a microphone array apparatus (2) toward a sound position corresponding to a position designated in video data on a screen of the display device (36) in response to a user's designation of any position in the video data displayed on the screen. The signal processing unit (33) forms sound collection directionality of audio data in the derived sound collection direction (θMAh,θMAv).

Abstract: A failure detection system includes an omnidirectional microphone array device having a plurality of microphone elements and a directivity control device that calculates a delay time of a voice propagated from a sound source to each microphone element and forms a directivity of the voice using the delay time and the voice collected by the omnidirectional microphone array device, and detects a failure of the microphone element. A smoothing unit calculates an average power of one microphone element. An average calculator calculates a total average power of a plurality of usable microphone elements included in the omnidirectional microphone array device. A comparison unit compares whether or not a difference between the average power and the total average power exceeds a range of ±6 dB, and determines whether the microphone element is in failure based on the comparison result.
