Abstract: An audio privacy processing device includes a microphone array device that acquires audio from a person in a designated audio pick-up area, and a signal processor that receives the acquired audio over a network and determines when an audio position of the person is within a privacy protection area in the designated audio pick-up area. The audio privacy processing device also includes an audio analyzer that analyzes speech audio of the person in the privacy protection area and determines an emotion of the person based on the analyzed speech audio by accessing a privacy protection sound database that includes emotion value tables, and an output controller that outputs a designated substitute sound and designated frequency from a speaker in place of the speech audio of the person while the person is in the privacy protection area.

Abstract: A sound and video processing system includes: a display that displays a video image captured by the camera; a sound collector that collects sound; an input device that receives designation of at least one designated location in the video image displayed on the display. 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 the at least one designated location. The processor displays at least one identification shape at the at least one designated location. In response to receiving re-designation of one of the at least one designated location by the input device, the processor outputs audio data in which emphasis of sound stops in a direction from the position of the sound collector toward the position corresponding to the re-designated location.

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.

Abstract: A camera and a microphone array configuring a monitoring system are capable of receiving electric power from a PoE apparatus through a LAN cable. In a case where a first switching operation is performed on a microphone array side, an output terminal of an input switch is connected to an input terminal of a PoE electric power reception circuit side. An input terminal of an output switch is connected to an output terminal of a PoE electric power transmission circuit side. On a camera side, an output terminal of the input switch is connected to an input terminal of a PoE electric power receptor side. The microphone array receives electric power that is supplied from the PoE apparatus for operation and transmits the electric power towards the camera. The camera receives the supplied electric power from the PoE apparatus through the microphone array and the LAN cable for operation.
